What Oil?

[87CamryTan]

Im about to do an oil change on my Camry and when I looked up the recommended oil on a parts site it said 20W-50? That seemed a little heavy to put in, was wondering what you guys use that makes the engine run the best. It's a 2.0 4 cylinder. Thanks.

10W-30 is fine to use, 20W-50 is heavy.

There was a thread just like this started a few days ago entitled "Oil thickness".

He is right. I live in the P.R.K. too and my opinion is use what toyota says to use within the lowest expected temperature before next change. Here it is already warming up and winter's over, 10w-30 is fine.
According to bob the oil guy thinner is better because the critical time for your engine wear is at start-up. You may have heard that one cold start equals 500 miles of highway driving in engine wear. This is approximately correct and the idea is to get oil to your bearings as fast as possible after a cold start, since most of the oil is in the pan. Thinner oil gets to the bearings faster, sure 20w-50 will get thinner the warmer your engine gets, but by then it is a bit too late, the critical time of start up has come and gone.

I always warm up my engine especially when cold and I don't care what anyone says, it gets a minimum of 20-30 seconds when warm and a minute or two when cold to warm up, pretty much always. It makes no sense to put a load on the engine at least until the oil has reached all the bearings, and that takes at probably anywhere between 10-30 seconds on a cold engine.

i have disassembled plenty of engines and seen what poor lubrication vs. proper lubrication does to/for an engine. Every little bit of help i can give the engine i will do, in order to drive this thing to the wheels fall off and not have it cost me any more then necessary.

Just because your oil light goes out is no guide whatsoever, that light will not come on until it senses less then 5 or 10 psi of oil pressure, and the light goes out at the same pressure (a healthy engine would be reading about 40 psi even at idle).
If you had been running 20w-50 and then switch to a 10w-30 or 5w-30 (if recommended), watch how much faster the oil light blinks out when you have the thinner oil in the pan.
