Engine oil Mobil or RED LINE

I use Mobil in my economy cars but Valvoline in my drift car , either oil is perfectly fine tho tbh

I always get the cheapest oil with the correct specifications. I use that mobil1 in my hybrid Camry. Works great.

I use Mobil 1. Meets MB spec and can get 5 quarts at Walmart for $30.

I used to use Mobil 1 in my IS 350. I can confirm my engine was quieter on cold stars when I switched to Ultra Plat.

I run Red Line oils in my H-Ds and Indian.

Mobil1

Owner of an often abused 250k+ mile 2002 Outback here. I use Mobil1 full synthetic 5W20. Runs like a top.

Get the Redline 5W-30…you won’t be disappointed. I was floored by how much better my Z performed with this oil. I’ll never use anything else.

Usually, motor oil goes bad because the additive packs that are in the oil get burned off or used up. I'd imagine that this new Mobil1 Annual Performance has more additive packs than what standard Mobil1 has but it's probably able to go that far because you're going to have to add additional oil that gets burned off because every car burns oil.

Engine was noisier with the mix vs. the previously used redline 5w40. Iron levels are up at 6.3 ppm/1000 miles Oil usage increased by 1/2 quart over the redline 5w40 TBN/TAN levels are worse than 5w40 at comparable mileage
