Engine oil VALVOLINE or PENNZOIL

For the last 17 years I've run the recommended Valvoline Blue in all of my Cummins and so far the internals have been spotless when looking inside.

Using penzoil ultra platinum 5w30…cheap and has been great!

Pennzoil 10W30 full synthetic oil was perfect for my S2000 in CA 0 issues it's also very cheap

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

Sounds very nice.

'03 GX470, had 240K miles when I bought it just over a year ago. Now on my 2nd oil change at 245K miles with Valvoline High Mileage 5W-30 full synthetic and Fram XG3600 filter. It's quiet and doesn't burn or leak oil.

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.

Valvoline Advanced with black Wix filter!

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).

Valvoline 5w-30 full synthetic for good cold starts in winter and a royal purple oil filter for good small particle filtration.

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