Engine oil Mobil or Shell

Mobil 1 full synthetic and Mobil 1 filter. I did cams recently on my GT and at 150k, the top end looks almost new.

I use Shell Ultra Helix 0W-30 but I mean I drive diesel idk how it looks like for n20 or b48 engines

I’ve been using Mobil1 0w-30 in it for over 20 years. My Blackstone Labs reports still come back clean with no water, fuel or antifreeze found in the oil.

Brings me back to my WRX days, we all used to run Rotella T6 because it burned less oil thru our gigantic subaru ring gaps.

I always used Rotella 5w30 gas truck oil designed for “All Mileage” in my 2005 Nissan Frontier with 95k but it’s been discontinued. I really liked this oil as it seemed to be thicker and remained viscous for longer compared to others. My favorite part about it? NO LEAKS!

What brand oil are you using? I noticed a decrease in consumption with Mobil 1 and stuck with it.

Mobil one..yes they make ac delco oil, but the additive package is a little better with m1 vs Delco.

Mobil 1 hands down. There's better but not as consistent for the price.

I’ve been using Mobil 1 in all of my vehicles and other equipment for 20+ years, never had a problem with it at all.

I have ran mobil 1 0w-40 for a long time without issue but am thinking of switching to thicker this change as it's starting to leak out one of the oil seals into compressor housing.
