I bought a new 1994 for ranger with a 2.3 4cyl engine. I took it home from the dealership and immediately changed the oil to Mobil 1 full synthetic. I change the oil every 5 to 6 thousand miles. Now the truck has 300,000+ miles on it and still uses 1 qt of oil every 4k miles since it was new. Oil psi and not changed. I am not nice to this truck, I over load it all the time. I did crack a valve seat at about 250K miles and I fixed that myself (40+ years experience in auto industry). While the cyl head was off I noticed all 4 cylinders still have cross hatch showing in each cylinder and no ridge. All my rigs use Mobil 1 exclusively cars, Trucks, Motorcycles.... Also, I replace air filters every other oil change. Never once have I had an oil related issue with any of my vehicles.

Best full synthetic oil on the market I’ve been using the soil for 15 years plus looks almost as good coming out as when you put it in. It does not break down easy it still seems to have a lot of life left in it and a 5000 mile oil change even if it’s been used hard I would recommend this oil to anyone

BEST OIL I USE IN MY 2018 FORD F150 V8 5.0L !!!

Slick stuff. Keep the engine bearings from eating themselves.

as always, does a great job

Best deal around on this oil when you catch it on sale!

Good price convenient packaging

Never had a problem with this oil

Mobil 1 is the best oil for today's modern high performance engines. I always stock up when it goes on sale at Sam's.

Tried other products but stick by the Mobil 1. A big fan, they have just what I need and can find just about anywhere.
