I use this in a 2008 Nissan Rogue SL AWD with 235,000+ miles on it and have used it in the transfer case and rear differential since it's first gear oil change from brand new. Still looks clean after 30,000 mile change intervals. Also use it currently in a 2008 Nissan Titan front axle, 1995 Nissan D21 pickup rear differential and farm equipment gearboxes, all at 30,000 mile or 2 year change intervals regardless. Moisture and corrision reduction and piece of mind. Exceptional gear oil that does what it's supposed to do. Lubrication, Protection and Longevity. Valvoline Synthetic gear oil is even better I'm sure. I just don't use Synthetic gear oil unless required by manufacturer. This conventional stuff is just as good!

1998 Ford Ranger (4 cyl open diff). The first change was at 110,000mi. Just now did another cover off change. I'm wondering now if I wasted my time because everything looked so clean. Very little smooge on the magnetic oil fill plug. Both times I cleaned it out with brake clean and air pressure.

I used this stuff on my 07' Crown Vic with the Ford 8.8, was super easy to refill my diff after replacing axle bearings and seals! Recommended! Didn't even drip any on the driveway!

Would definitely check your car's underside first before buying this. On my IS300 it was a pain to reach the inlet. Tried the simple route to the fill hole but the angle was too sharp and the lid popped off. Lost almost half a bag. Had to stuff it over three steel frame parts while securing a screw to the tip so wouldn't lose the rest of it on the way to the fill hole.

Motor fit, although it wasn't exactly like the original, did not have metal shielding on the bottom, and original shielding does not fit over the modified plastic molding on the bottom of the replacement blower motor. It has performed flawlessly so far. I'm still leary of the heat produced by the motor without any shielding, but I'll keep an eye on it.

Mobil 1 full synthetic first time using. With all the good reviews I'm switching from Valvoline high mileage which I've been using for 20yrs. I have Toyota 2010 matrix with 140,000 many more miles with this oil and not doing oil changes every 3,000 miles I seen between 5,000 & 7,000 I drive 400 miles a week to work and back home!!

Folks...there is a reason why corvettes require this to maintain warranty. I have used Mobile One for the last 20 years. RECENTLY, I had a 2.0 L turbo buick regal. I never had any issues with it and sold it with 190,000 miles. The yound man I sold it to is still driving it 2 years later. I use it in my trucks, my two sports cars (Dodge Hemi 5.7 and Chevrolet Camaro), my lawn mowers and have not had one single engine problem or issue. I would call that an unparalleled success. Thanks to the Chemists and other folks who have put such an awesome product on the market!

I began using Mobil 1 oil when I took a job working as a lubrication "chemist". I was not a R&D pro, but had technical skills from other scientific disciplines and was charged with buying equipment and starting a lab. I had lots to read, learn and understand but was quickly impressed that virtually all synthetic oil manufacturers would compare their products to Mobil 1. (All trying to measure up and catch up). I retired 13 years ago and have no reason to change from the brand that I trust.

see above comment...Mobil #1 is the best oil available for enhanced engine protection w/ reasonable pricing associated with it after reading many on-line internet peer reviews....unlike "Amsoil" which is greatly overpriced for the additional unneeded over protection it provides.

MKZ hybrid with 133,000 miles. Always used Mobil 1 extended performance and Mobil 1 filter. Well worth the extra money when you consider it doesn't need to be changed for 20k miles. Oil always looks good at Oil change and no issues at all with engine, no leaks, doesn't use a drop of oil after 133k miles. I attribute this to always using Mobil 1 extended performance Oil.

Changed my oil, ran my engine to check for leaks all good. Waited 30+ min to let everything cool down and changed the filter, ran the engine again and everything spurted out of the filter area only. Remove filter checked everything and there was no noticeable problem and filled the filter back up, then put it back on perfectly. Ran the engine again and same thing again. Long story short I put the old one back on and everything worked fine
