This may sound naive but to check the oil properly, should I check when the engine's cold like 1st thing in the morning or should I run the car for 30 sec or so, then turn it off, then check.

Along those lines, to check air pressure in tires, I always heard to check when cold, not after the car's been driven for a while. I typically do it before I get in, 1st thing in the morning before driving.

Am I doing these things correctly?

TIA

Oil warm, tires cold.

Oil: check when car is at normal operating temp, not just after running for 30 seconds. I do it upon returning home after a drive.

Tires: check when cold, i.e. not driven for at least several hours. Also, ideally, first thing in the morning before the ambient temp has risen. The idea is to get a true "cold" reading, which will increase due to both increases in ambient temp and to tire temp due to driving. Get a good quality tire gauge, preferably two so you can check them against each other. I use Accu-Gauges. And don't forget the spare!

Thanks, just what I was looking for!

Car is at normal operating temp. You DO turn engine OFF,then check oil level, right?

Bill S

You are correct!

Thx again.

OK, if you've got different profile tires than the stocks, how do you find out the right psi to run?
