Rated 5 out of 5 by from Good Oil Good oil! A little expensive but I'd rather know I'm putting in the good stuff than taking it to lube shops with cheap oil and high service costs. Mobil 1 all the time!

Rated 4 out of 5 by from Installed in 98 Grand Marquis It seemed to help with oil loss(1 qt/1500 now 1 qt/2000) but I'm replacing lost oil with 5W30 instead of 5W20. Valve cover gaskets have very, very slight weep and I'm not sure if the oil made a difference.May need more time. Oil looked a bit dirty after 2000 miles. 5W30 was originally speced for this car and after all these miles it is probably a good idea. I'm concerned though it is only an SL oil and it don't meet Ford specs, nevertheless I'm sure it is a good product. Car averages about 22Mpg, about the same as the OEM Ford Oil. Does not increase or decrease mileage. Informally I can say the engine feels extremely smooth and relatively powerful when idling, passing, accelerating, etc. It ran fine with the the other oil but I can tell a difference, almost like a new vehicle. Seems to start easier as well, even on a cold morning(25 deg) it is running after one click. Car has 150K.

Rated 5 out of 5 by from Long relationship with Mobil 1 I've used Mobil 1 on my Mazda protege at 65,000 miles to 450,000. Ford Explorer sport trac lasted 350,000 then sold. 2008 Mazda 3 from 10,000 to 100,000. My son's Mazda speed 3 up to 100,000 miles so far. My brother's Mazda 636 lasted 430,000 miles. I've raced 1000cc and 600cc motorcycles for the last 5 years with Mobil 1 oil and let me tell you I'm a big fan, I've had to look into a rebuilt engine for a race and all parts were excellent condition, every vehicle I own I use Mobil 1, it's definitely worth my investment.

Rated 1 out of 5 by from Made My RMS Leak Worse I was using Valvoline MaxLife before switching to M1HM. The RMS (Rear Main Seal) was leaking just a little bit. A friend recommended M1HM and he stated it would most likely stop the leak. Well, the leak has gotten worse since using M1HM. I am switching back to Valvoline MaxLife

Rated 5 out of 5 by from The Best Oil I have a 2005 Dodge Grand Caravan SXT with 227,000 even in -14 degree temperature in Michigan. My Dodge van purrs like a kitten, and transmission shifts like a champ! Thank You Mobil 1
