Like the title, what do you use? I went from 10w-30, up to a 15w-50 for my last one, and it made me sick when i started it up and started driving it, so laggy, i hated it. Next change will be right to what the oil cap says on it, 5W-30. And of course, synthetic, i don't put normal mortor oil or mix's in my car.

5w30 castrol syntec

I have high mileage (180,000)
and every body is telling me
to switch from synthetic to regular
good idea?

15w50 Mobil 1 synthetic.

I'll most likely drop down to 10w next change, 15 seems a lil excessive.

i thought it has to do with your location as to what grade is best for your car, i live in the south (MS), and everyone is telling me to def. not use synthetic, cuz it will tear up your engine, i don't understand this and think they are all hicks and don't know hat they are talking about, my dad has always used 10w 30, but my car will be used for racing and have no idea what oil to use, and how often to i change it, i know its normally evry 3000 or 3 months, but i have heard to change it about every 1500 if it is being raced, and as far as when you first put in a motor, how often do you change it, it is a rebuilt motor, someone here told me to just wait till I finish breaking it in (going easy on it till 2500 miles) and then change it fo the first time, but a friend said he changed his like every 500 to 1000 miles until it was broke in with his new engine, he says if you don't it will tear up your engine faster

thanks for any help with the matter

I use Mobil Drive-Clean 10W40 in my car. I may switch to Mobil1 full synthetic soon, but I'm not sure...my engine, like most AE101 4A-GEs, burns a small amount of oil(like a fifth of a quart every 800-1,000 miles), and I'm not sure if synthetic would make that worse because it can penetrate where regular oil can't.

castrol syntec 10W 40 I think one of my seals in the turbo is toss i'm getting a little oil in the air filter tube

If ne one is interested, heres something I read from the Alltrac forum, its long, and gets complex, but its a good read.

Synthetic Oil Myth

ah i just uhhh kinda mix um around well, when i had my celi. it burnt oil a lot anyways. i usually mixed some 20w 50 in there a a little straight 30 weight. but it was mostly castrol 10w 30.

Straight up Mobile1 fully synthetic 10w30, with mobile one specially designed synthetic filter. Costs 40 bucks a change but its worth it.

10w30 Synthetic the Advanced Auto Parts brand, and then use two of those Engine Restorer bottles so it averages out to alittle less than how much it cost to but just Synthetic put in, and those Orange Filters, forget the brand...

but i change my own oil so it cost alittle over $20 bucks to buy all the oil and i change it ever 2500-3000miles (drive my truck hard, needs it changed that much >> )..

so what exactly should i use in my 3sgte if i live in a very humid area. and how often should i change it

I use VR-1 Racing 20W-50. Works great and lasts long...the engine burns around a quart every 3-4 days. >>

toyota recomends 10w30 for a 3sgte.
