Engine oil PENNZOIL or Lucas

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'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.

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).

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

Pennzoil Ultra Platinum is one of the best full synthetic oils out there.

Liqui-Moly is also good, as are Amsoil and Pennzoil Ultra Platinum. I never had good luck with Mobil 1.

I keep a running supply of pennzoil ultra platinum 5w30 around as 4 of our vehicles use it. I start to worry when I have less than 10 quarts.

Pennzoil because it runs about 20°F colder for me.

Pennzoil. I've run conventional, semi synthetic, and full synthetic. Nearly 200k miles, still kicking like a mule. 7500 mile oil changes on the reg, some to 9000. No signs of slowing down.

Pennzoil ultra platinum often goes on sale or has rebates, I'll stock up a couple years supply when it does.
