What oil manufacturer makes the best one /o/? Not counting some

>>16936288
They're pretty much all the same in terms of quality. Castrol is a really good brand. Don't settle for no-name or off-brand chinese shit as thats absolute garbage.

Any recognizable brand such as Mobil, Valvoline, Penzoil, Castrol, etc are good brands

A lot of different tests show that one brand thats perhaps 3rd in one test is the 1st in another test

What I care mostly about is that its certified, and its weight/viscosity when its cold. On the last point I've seen a few tests where they pour same weight oil (5w40, 0w40 mostly) thats been cooled down to -25c/-13f from different containers equally, to see which is more fluid; Mobil1 wins every time

I use penzoil 5w-30 high milage in my truck. Gets the job done, it's the right weight and my local parts store carries it.

>>16936288
Supertech is $11.35 for 5 quarts. Been using it since the 90's and no troubles.

>>16936288

Changing your oil is a shit boomer meme, modern cars don't need it

Quart of mobil 1 every 6 months or so because the motherfucker slowly leaks it all away

>>16937375
Modern cars need it more than ever due to the narrow tolerances and increased efficiency of the engines.

Old ones needed it because the oil was shit quality and would goop up really easily.

I'm a retard. If a fluid is more viscous, is it "runnier" or thicker than a fluid that is less viscous. In other words, Is viscosity a measure of the runniness or stickiness of a fluid?

i use quaker state full synth, everything seems to be going fine atm. recently bought a used vw and wasnt sure if the previous owner was using FS so I went ahead and started using that.

Yes higher number is a thicker oil


Or a higher viscosity

A double rated oil eg 10w50,5w40 is a measure of viscosity in different temperatures like 10w50 will be the higher number in a lower temperature and the lower number in a warm temperature

They've recently started using lower grade base oil for their stuff. Because in the US your oil only has to be a group 3+ base in order to be sold as a full synthetic.

Also the continuing demand for oils that preserve fuel mileage and don't fowl emissions equipment is killing modern oils in gnenral.

>Mobil1 formula got recently changed and they actually made it worse.
The 540RAT oil database has test results for various oils. Retests are done for oils every now and then because oil formulations change. Some oils go up, some go down, and some never really go down but later may go up. Pennzoil platinum and mobil1 synthetics were ones that went downwards in terms of absolute PSI score.

Can you go one year between synthetic oil changes if you never even come close to the mileage limit?

>>16940881
Depends on your driving and environment. Should usually be okay though.

cheapest oil you can get.
there is absolutely no difference.

>>16940957
Pretty much this, long as it's got an ASE stamp on it you're set.
I like rotela t6 tho since it works in my motorcycles and my cars and trucks, one oil to handle everything.

On measurements, pennzoil is generally the best

Doesn't entirely mean it'll make a big difference, but it's cheap as the other oils

>>16936288
What ever cheap 10w-40 they carry.
Not even putting 4T oil in my bike.

>>16940963
SAE* lol

>>16940963
I use what the model specific autistic recommend on model specific forums. For my Saabs that is rotella t6. In my Jeep I now use some high mileage, I forget the brand, used to use mobile one. When I get a boxer I'll use what they recommend.

I prefer Pennzoil Platinum because it scored the best according to some completely arbitrary and unrealistic tests done on a site I forgot the name of. That's good enough for me, as long as it's full synthetic and not some no-brand shit it will probably do all the same. I can't help but notice my oil PSI has gone up about 15 PSI after ~2 weeks since adding Pennzoil's High Mileage so that's cool. Either it's unusually thin or it really is cleaning out the engine like it says its designed to do.

>>16936288
Super Tech from walmart. Rebranded quaker state

>>16941203

That's not really how oil pressure works....

Low oil pressure is caused by excessive clearances or leaks. High oil pressure is caused by restrictions.

So by gaining 15 PSI of pressure, that essentially means your fancy new oil is causing a restriction somewhere, probably clogging up a screen or filter somewhere with all the junk it's flushing out.

Think of it like this - you try to put 100 gallons of water through a 2" hole in 30 seconds, you have an arbitrary pressure value. You put the same water through a .5" hole in the same amount of time, does your arbitrary pressure value go up or down? Same thing is happening in your engine.

>>16938580
It's actually slowing down your fiesta, because it's too heavy for your 35 torks to carry on the Pistons.

>>16938580
I bet your oil temps have never once seen racing temps.

10w40, whatevers cheapest, my cars only worth like 300.

>>16941292
I'm expecting it to have clogged the shit out of the filter, it has had around 140,000 miles of shitty conventional oils all changed by mechanic shops who just recycle old oils of mystery weights instead of giving you actual new ones. Gotta get it out somehow, but I'd hate to change the oil and filter twice in two months with my current budget.

>Rebranded quaker state

I run an Oil Change shop.
Basically, as long as your oil meets norms specified by car manufacturer, its good enough. However, putting better oil in your car can and will increase its lifespan. For example, synthetic oils clean the engine much, much better than regular dino and semisynths. They also are more resistant to pH changes (important if you're driving on LPG) and store sud more effectively (important for diesel engines).

Brands that I run - Castrol, Motul, Total, Elf, Mobil, in order of popularity.
In order of quality - Motul, Eni (I don't sell it for some time now, but still, very good oil), Valvoline, Castrol, Total/Elf, Mobil.
Also, Total/Elf make the best gear oils, period. Motul takes second place, Castrol third.

For filters (since its kinda relevant) - get Mann, Mahle, or Wix/Filtron. Avoid Bosch.

As for that Castrol vs Mobil on definition of synthetic oil shit - it really makes a difference. Basically Castrol stated that hydrokracked oils should also be named as synthetics.
What does this mean in terms of oil quality? Hydrokracked oil will rarely be as good as fully synthetic one. Anyway, most of Castrol lineup is hydrokracked, but named as synthetic, whereas other manufacturers state if the oil is kracked (HC Synthese, Technosynthese, synthetic technology etc) or full synth.
A lot depends also on mineral base used in the kracking, the better the base, the better the oil will be.

>>16942853
What metric are you basing the quality of oil on? Are you also generally assuming a 5W30 when you rank the brands?

FRAM filters or nothing.

Thanks fram you da best.

Castrol errrry time

>>16942914
I base quality on pragmatic experience. For example, lets take my customers car, BMW e60, 3.0d. Over 500kkm on the clock. Oil changed every 15-18kkm, up till a year ago it was Castrol Edge TD 5w40. Sure enough, engine runs ok. We change the oil to Motul X-Clean 5w40. You know how in diesel engines, oil gets black right after change? As in you put in new oil, you run the engine for 30 seconds and check the level, its already black in most of the cases? Well, on second Motul change, it did not get black for over 800km, only gradually. What does that mean? Motul cleared the sud that Castrol failed to clean, stored it, and most of it went out with drained oil. That means quality for me, measured in something else than just manufacturer norms (both these oils meet BMW LL-04 norm). Other stuff, same car - engine runs smoother, and gets better mpgs. Customer has this car for over 6 years and made most of the kms on it. I trust that this is not just placebo effect.
So far none of the customers we switched from various oils to Motul said they wanted to go back to their old brands.
Motul quirk - engines eat it more than other oils. Not much more, but they seem to do so.

I also compare oils by viscosity, yes, so I compare 5w30 to 5w30, 10w40 to 10w40 and so on, but when Castrol (here at least) has only 2 10w40 oils (Magnatec and GTX), both of which are quite expensive, both of which meet at most API SL/CF norm, Motul has 3 10w40 oils, the 2100, which meets same norms as both Castrol 10w40's, the 4100 and 6100 which meet higher norms, also the 6100 is hydrocracked oil. That means its synthetic technology oil, not your regular semi synth, and it meets API SN norm.

>>16943043
Thanks for a legit answer on /o/

What about the formulation makes Motul better in general? I'm guessing that kind of info his all proprietary, so you may not know. I'm just curious how two oils that meet a certain base standard can still perform drastically different.

>>16943102
cont... perform drastically different and you aren't paying a huge premium for it. Motul isn't that much more expensive from what I've seen.

>>16943102
>>16943113
I do not know formulations, that stuff is never explained to us, we only get the marketing blablabla our stuff is better. But I have the means to actually check it, as in my customers (those that clock many kms) report if their engine actually runs and feels better, or gets better mileage.

Castrol quirk - Magnatec stuff really works, we've taken apart 2 engines that ran on Magnatec 5w40 and they were covered with oil inside - as in a thin layer of oil stayed on the engine surfaces long, long after it ran (in second case we took the engine apart after 3 days, and we did not run it during this time).
Another Castrol quirk - their Edge lineup seems to have gotten better with that Titanium stuff, but I do not know if its titanium or they got their shit together.

>>16943183
Doesn't matter. Loose tolerances on mover engines. Get Briggs&Stratton 10w30 for cheap, Magnatec is expensive.
Oil change shop dude off to sleep, cheers.

>>16943043
So am I to understand that Motul will effectively suspend all of the loosened contaminants between changes to the point where it will be okay to drive a full 4-5k miles between changes, and still get a good flushing effect?

Or should I do a single Motul "flush" per se by only driving 500-1000 miles on the fresh oil and replace it again, for maximum sludge removal?

I noticed that my fresh Castrol GTX High Mileage oil did indeed turn black within a single journey from my workshop, approximately 17 miles on the freeway.

Will sticking with Castrol and rapidly changing (<1000 miles) to another fresh batch do the same thing? I'm worried I won't be able to find this Motul brand near me.

I live in Ohio.

>>16943137
Thanks again. Do any of your customers track their cars or put them through heavy duty, high rpm use? If so what oils have you observed with them?

I'll try the magnatec. My toy car tends to sit around a lot, and that thin layer definitely would make me feel better when I fire it up after awhile.

Tbh it all depends. Each brand has its pros and cons. I have a gti mk 7 and its weak point is carbon build up. So i use liqui-moly as its the best oil for preventing it. But castrol for exaple has the best anti wear and drystart protection. Vqlvoline last forever... from a 18000 mile oil change experience on my girlfriends car i can vouch for it. So on and so forth. Look into each oil and also your car. Figure out its weakness and get an oil best siuted for your engine.

>>16943249
You can do engine flushes with stuff like seafoam or LiquiMoly engine flush for example, but flushing engine that runs on mineral or semisynth oil by using synthetic oil is a bit different.
You don't exactly flush the engine, but simply allow better oil to clean it better. For example, if you run Castrol GTX 15w40 in your engine, just use Magnatec 5w40 on your next change. Don't worry much, just check the level every 500-1000km, it should rapidly eat about 0.5-1L of it at around 8kkm mark. Then you can either add oil and change it at recommended interval (btw, we recommend 10kkm for mineral, 12kkm for semisynth and 15kkm for synthetic oils), or change your oil and stick to 5w40 and 15kkm interval now. You might notice increased oil use for first 2-3 oil changes.

>>16943249
Oh, and do not mind too much about brands. Motul is indeed top tier, but its often not really worth to go that extra mile, just put whatever synthetic available you have, Castrol or Valvoline will do good enough job too. Unless you track your car, spending way more money might not be worth it.
>>16943272
99% of my customers are your everyday Joe, I recommend Motul to them simply because its not that pricey here. But some are dead set on their brand of choice, I don't insist too much as it doesn't matter too much in simple dd ecobox.
For that 1%, we almost always recommend Motul. In one case (Audi RS2) its 300V 5w30, heavily hooned but not tracked. Same dude, Kleber tuned CLK, X-Max 0w40, also hooned from time to time. His 964 runs on Helix HX7.
Another one, runs 1.2 Cinquecento in rallies and 1/4 mile, says he shaved 0.3 seconds of his 1/4 time by changing gear oil from 75w90 to 75w80.
But those customers are very rare. We're regular oil shop, not tuning garage, so its understandable.

Whenever i get a new shitbox i buy 20-30l of the cheapest ok oil i can find and i run it hard with a few hours, change the oil, rinse and repeat.

Once the oil starts coming out clean you've flushed your engine properly.

>>16943445
Should be ok, but most movers use 10w30 oil.
>>16943483
We don't get their premium line here. Normal one were ok up till a year ago, then they lost their quality. Not only filters too, brake discs/pads, electric parts etc, everything by Bosch became worse:/
>>16944728
I only speak about stuff I work with, we have no Redline oils here.

>>16946174
That indeed is one way to do it.
Though engine flushes are safer and cheaper IMO. If you really want to do a cheap flush, then put oil to the engine just below max, then add 300-400ml of diesel. Run it on idle for 5 minutes, change the oil. DO NOT put any stress on the engine during that time, only idle running. Though I do not really recommend that method.

>>16936288

Oil change ship dude, if you are still around. What is the main difference between Magnatec and Titanium? That Magnatec is semi-synth and Titanium is fully-synth? (At least in Germany that is, in the UK they are both synth? How does that even work?)
I have Titanium in my car right now but since I drive A LOT of short distance trips with occasional long one wouldn't it be better if I went the Magnatec route?
