Engine oil Mobil or PENNZOIL

mobile super 3000 w0-30 is what i would run if i were you

South Florida, 2010 GX460 @ 90k miles. I use Pennzoil Ultra Platinum 5w30 year round and either a Wix or OEM filter.

Sounds very nice.

I use Mobil 1 in my RT and it's been good.

I've run penzoil ultra platinum 5w30 for the last two oil changes. It's great, but running the heavier grade oil I notice the engine is a little sluggish until it's been running for something like 10 minutes, so my next oil change im gonna go back to 0w20 and stick with penzoil ultra platinum because it seems to run cleaner than the valvoline oil I ran before.

Mobil 1 0W20 every 2.5k miles.

I do penzoil. Amsoil is good stuff too, penzoil is just easier to find. I do the ultra platinum. And I use wix filter (black one because it has the same valve the oem filters have).

I've had my '88 GLI 16V for over 20 years and always used mobil 1 15W50 without issues.

Mobil 1 since day one (first oil change). 5w-30 (as per vehicle spec). 316k+ original owner miles. Virtually no carbon or varnish.

My car burns oil and I went to Pennzoil ultra platinum. Burns ways less oil now

I will say after switching to mobil1 in one of my rigs it cleaned out a hell of a lot of shitty carbon deposits and crap in the valvetrain. Looked nearly new when I pulled the valve cover at 210 thousand miles.
