Been using and trusting Mobil 1 5W-30 for over 30 years in all my cars and trucks and not once had any engine problems or failures. Great product.

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

[This review was collected as part of a promotion.] It was the best price! ($10 less) than anywhere else around.

I have Used Mobil 1 for years. Factory fill for Nissan GTR and recommended by Nissan for their other vehicles.

Excellent oil and is sold at a good price. Makes my cars run smooth. My store is always out of it. So, I haven't purchased any in months.

Good Stuff. I've used this for about ten years, maybe longer. Three different vehicles. Never a problem.

I always use Mobil 1 in all of my European cars and have for years. My cars all run great for over 150,000 miles!

Its a solid oil. Full synthetic is what is required in multiple vehicles i own and ive been running it for close to a decade with no issues.

Been using Mobil 1 for 20 plus years never no problems no fuming break downs use it in my cars and motorcycles

I have been using Mobile 1 since the 1970’s. Knock on wood. I have never needed an engine repair because of oil related issues.
