I've used Mobile 1 oils exclusively in my performance cars and daily drivers for years. It always comes out as clean as it went in, and never have had an issue with sludge. Definitely the best oil if you want to take care of your engine.

I had a 2006 CRV, traded it in at 300k. I kept up on maintenance religiously. I used Mobil 1 and changed every 10k, the car never was in the shop. Very good oil.

Have had excellent results using this product. It has given me confidence in engine protection and good results in fuel economy and no significant oil usage between oil changes.

It’s ok. I’ll be switching to amazon basics oil for my changes. Lower price and meets all the same specs, even beats it in the cold flow test and it’s cheaper

I used Mobil 1 5w/30 for 12 years and 260,000 miles in my 04 GMC 2500HD. Changed the oil between 6500 and 7000 miles. The engine outlasted the rest of the truck. Enough said.

I've have used Mobil One 5W20 since purchase of my new 2011 Toyota Camary , I was shocked as I found out ( damaged oil pan ) leaked out ALL ENGINE OIL from a returned trip from Texas to California!!! Over 1800 miles with no Damage to engine!!

I have a 94 camaro with 267,000 miles. I have used Mobil 1 in it since the car was new. I replaced the valve cover gaskets last month and the rockers looked new. I will only use Mobil 1 in my other vehicles also.

I have 2001 Lexus RX300 which my miles its already been 380,000 and my car has excellent performance until now i had been using Mobil 1 5W-30 since the first change oil until now.
