I'm about to put 4 new quarts of conventional oil into my

Five quart jug of most brand name full synthetic oils currently at my local usa wal-mart for $23 to $25. So when you say synth is $15 more, that's quite a shock. The wal-mart house brand full synth is $17.99 for a five quart jug.

Change it before 3k miles. Conventional will sludge up in these tiny gokart engines.

you just lost 50 torques

>>15924860
Not very just be sure to change sooner than synthetic. It's oil and you changed it, your car won't know the difference.

conventional is 3K miles, full synthetic is between 5 or 7 depending on who you talk to (manufacturers usually say 5). Some people say 10k is still acceptable for full synthetic now.

shame I don't even have the option in my car, I'm running 0W-20

not sure if you guys are being sarcastic or not

anyway, i only have about 1k miles in the conventional oil, should i get an oil change now and replace it with synthethic? or just run it the 3k miles, kinda poor atm desu

>>15926156
Put synthetic, most cars don't need an oil change until at least 7k-10,000miles with synthetic. Fill it up with good oil, pay for it now and earn that piece of mind

>>15925659
I was always taught that 10,000 or so was fine with full synthetic if the car had been fed full synth its whole life.

Some manufacturers have turbo designs that have more "heat soak sludge" than others. So they require full synthetic oil to prevent the heat soak sludge problem. After all, it was the needs of hot running jet engines and racing car engines that caused full synthetic oil to be commercially developed in the first place.

It's easy enough for you to get a jug of full synth oil and do another oil change right away. Allow a longer time period to let the oil drain out. Your oil filter should be replaced too as it has conventional oil in it.

If it were my car, I'd do two full synth oil changes. The first one to get rid of most of the conventional oil. The 2nd one to get rid of the residual conventional oil that was diluted into the full synth oil of the previous change. Why do this extra trouble? Heat soak attacks the conventional oil and makes it gum up, so I used the first full synth change as a flush. I would use a higher detergent full synth to do the flush such as the cheapest full synthetic oil jug. Use that for 10 miles. Then do the 2nd full synth oil and filter change. The 2nd full synth oil change would be to pennzoil ULTRA full synth for the extra detergent action. I'd run that for the next 3000 miles. Then I'd go back to my usual mobil1 full synth.

If you did the oil change yourself, then the car company doesn't know you violated a warranty condition. Oil change companies report data to various databases. If you have a future warranty claim against the power train or engine, the company can point to your violation of the contract.

>>15925566
You do realize oil is designed around the engine right? Throwing anything in it is downright retarded.

>>15926278
what does your engine say to put in? I drive an 02 civic hatch it says 5w-20

I heard my car's engine burns oil, or VTEC burns oil or whatever. 1quart every 1,000 miles

>too cheap to pay twice the price for oil that lasts twice as long
>too retarded to use the recommended oil in the first place

>>15926866
Once it sludges up, can it even be flushed without getting the oil passages plugged up by the gunk? It'd be terrible if the head (and thus the head gasket) has to be removed and wires shoved down the oil passages to unplug things.

>How fucked am I?
you are fine, if you had a turbocharged engine you would need to change it within 3k miles.

If you have variable valve timing engine it might start to get angry, but i wouldn't worry till 5k miles.

No problem. Just sell it to someone else as soon as things start to feel different.
