Engine oil Castrol or PENNZOIL

Dont use the cheap stuff. Liqui moly or Castrol!

This is what I use… with a Fram synthetic oil filter.

Pennzoil Platinum or Ultra Platinum 5w20 and WIX 57060 (non XP) filter. I bought my truck with around 40k miles, it now has 90k and have had no issues with the motor changing the oil every 7500 per Blackstone's oil analysis I sent in not long after I took ownership.

Pennzoil Ultra Plat.

I have been using 5w-20 for more than 3 years on my Accord 2004 (330K) and 2003 (230K). I have no issues with both and the engines runs the same as before using other oils like Castrol Magnatec.

My dealership usually overfills my car and I do not think they use Toyota 0w-16 based on oil tests I have done. I do my own changes and switched from Toyota 0w-16 to Mobil 0w-16 and landed on Pennzoil presently and going forward.

But as a fellow 7.5 owner i switched to 15w-40 when going stage 1 because where i live temps regularly even in winter are around 98-105 degrees and i was finding i had to top off the oil every 1,200 miles, since the switch to the thicker oil ive done 2,500 and the level is exactly the same

Castrol Euro in my mk6. It meets the VW spec according to the bottle. I've been using only that for 9+ years, changing oil at 10k miles or 1 yr, zero sludge, zero problems, original turbo, good compression, good oil pressure, etc. IMO it's very good oil.

I run penzoil ultra platinum. I’ll spend the extra money to know that I might get a few more hours out of my gen.

Castrol Power 1 isn't a bad oil, but I'd say not the best either. I have only used LiquiMoly as an alternative, so far and I rate is better than the Castrol but it did cost almost 2x as much too.

Castrol edge is junk.
