Engine oil VALVOLINE or PENNZOIL

I run Valvoline restore & protect because 2x 5 qt jugs fits my 4 qt Prius and 6 qt Maverick perfectly and I run it on the Prius which has stopped oil burning from the low tension rings.

99 Ls400 owner. Pennzoil Ultra Platinum every 5k miles.

Pennzoil Platinum Euro full synthetic 5W40 on my Abarth. Same weight as written on the engine oil cap and in the user's manual. 5l jugs easily available for $40 CAD plus HST.

Pennzoil Euro Platinum 5w40. This oil is slept on but out performs most other expensive oils outside of Amsoil.

Nice work. My 2012 camryil4 se gets new oil every 3k 0-20 pennzoil ultra syn. 112,000 mi.

Both of my Guzzis ran better on Valvoline. This is if you’re in USA

Penzoil Ultra Platinum 0-W20 @3-4K and Mobile 1 Extended Performance Oil Filter. I like that Penzoil derives their oil from natural gas.

I'm using Valvoline 0W-20 Restore and Protect, changing every 4,000 miles. '23 OBW, 56,000 miles. FYI, I did an oil analysis at my last oil change. Wear numbers were excellent, less than 1.5 ppm/1,000 miles. 3 iron, 2 aluminum, 1 copper over 4,128 miles. Fuel dilution was HIGH though, at 4.3%. They expect 1.5- 1.8% for direct injection turbos. According to the Motor Oil Geek, less than 5ppm/1,000 miles is considered good. I do a fair number of short trips, but also some longer runs. I'm going to go to max of 4,000 miles due to the gas dilution.

Legit. Worst case scenario it doesn't do anything, but I've seen some improvement in my Cadillac ELR. Engine is quieter and lots of sludge was removed. But fwiw lots still remains and the varnish is basically untouched.

BMW switched from Castrol to Penzoil years ago...but both cause oil starvation in The S65 motor
