Great product and at a great price

I have not used other products much and can't compare but after 200K miles (and 20 oil changes) the engine does not have any crud/buildup, all shiny like new as I just adjusted the valves and at least the cylinder head looks in excellent condition.

I’ve used it for years for all of the family vehicles. Change interval of once per year, usually 10-12k miles. It’s nice to only do an oil change once per year. Never a problem.

I commute 400 miles a week and Mobile 1 has kept my car running like new. I trust Mobile for all my vehicles including my motorcycle when I can find it. My local store was out of stock the last time I needed it.

Excellence oil, been using it exclusively for approximately 15yrs never had anything except great things to say about it. I will continue to use it as long as it’s made.

I use this oil in my daughters car and extend the oil change intervals to 10k. Car runs smooth and has no issues. Mobil 1 is my go to oil for all my cars.

Love this stuff. Of course it’s hard to say which oil works best, but when you look at the testing for the 20k mile extended performance it gives a lot of peace of mind.

Works well in my 2016 6.2L. Been using Mobil 1 for years and switched to it for my 6.2L after the first couple of dealer-supplied oil changes. Not using any oil and runs great.

I've been using this product since new in my Toyota. Ten years later - no oil consumption and oil analysis always shows below average wear metals. Consistent quality product-

I have been using Mobil 1 synthetic oil in my vehicles for more years than I can remember. I believe Mobil 1 oil and regular oil changes contribute to reduced engine wear. Thank you for offering a great product at a affordable price.
