Owner reviews for engine oil

I personally run the valvoline, seems to be a tad quieter on the valvetrain.

I recommend checking your oil level at 3000 miles because some vehicles burn oil. BMW and Audi especially, at 1500~2000miles I will top off.

I would do 10k intervals in my Honda Fit but a majority of my driving in that car was highway. I'd also need to add a quart after 7000 miles because of consumption.

I use Full Synthetic ( Pennzoil Platinum). At 24K I really can't even tell the engine is running when I come to a stop, its just that smooth and quiet.

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.

1.3 million on Amsoil. Shell is a close second.

The 2.3 liter engine on a ford ranger takes 6.2 quarts as opposed to my corolla that took less than a gallon for the 1.8 liter engine.

Funny, I changed my oil today for the first time as well. Also 1700 miles. Not black but certainly a lot darker than the Mobil One 0w40 that replaced it..
