best oil on the market broke a serpentine belt that stopped the water pump from work she drove it tacked on temp hand red lined for about 5 minutes no other oil would have held motor from blowing 2nd on list is Valvoline.
 But lasting 20000 miles it's stupid to not pay few more $ even tho I'd change it around 15000 miles motor runs like a top looks brand new inside with 262,000 miles on the car winter I run 5w20 summer 5w30

walmart.com

My 2014 Ford Taurus Limited with the 3.5L has lived its hole life using Mobil 1 5W20, and at 137,000 it's purring like a kitten. Change my own oil and use the Mobil 1 oil filter every 5,000 miles, and when it's ready for an oil change, my dip stick still reads FULL. New cars can't match that record!

My Mobil1 savior message

I have been using this on a handful of vehicles over the last several years.  Some since new and one used 1998 Civic the girlfriend got used with 225K miles on it.  I switched it to this oil and she made another 40K before losing the head gasket.  I was more impressed tearing the engine apart replacing the head gasket and everything as I went noticing how clean the engine was.  I have torn engines apart clear back in the 90's on conventional oil, and a few different brands of blends to full synthetics since.  This being the cleanest internal engine and components and I was expecting the worst since we got it 3rd hand used.  She only got another 20K on it after the head gasket, but that was not the oils fault.  Almost 300K and the last roughly 60K was on this and kept it clean until it was just worn out and broke.  Had to tear into the riding lawn mower I got new in 2008 been running M1 Extended in since new and lost the head gasket on it in 2022.  Internals looked amazing and is still going strong today averaging 100 hours a year on it for 18 years.  My work truck doesn't burn any oil and over 120K miles running it since it was new.  The only other oil I feel is a fair comparison is Amsoil.  This has been a great product and highly recommend.

Excellent Quality Oil

This motor oil is great! I've used it for over 20 years in all of my vehicles, including a race car. I also use it when doing oil changes for my friends. Walmart offers the best value for a 5 quart jug that cost $10 less than any Automotive store.

Mobile one for the win.

Mobile makes the oil for Honda and this oil is of the highest quality. If you have a high mileage Honda, this product should be your first choice after Honda OEM oil.

Great Oil For High Mileage Vehicles

5 stars for Walmart delivering the item ahead of schedule.  One slight concern was that the jug was in a bag that had no packing for protection.  Luckily, no damage.  Can't comment on the oil itself, seems like it doesn't get as dirty as quickly as the other Mobil 1 oils, but really can't tell.

Happy camper

MOBIL 1 (5W20) MY 2005 LINCOLN LS RUNS ON THIS OIL %26 ENGINE PERFORMANCE IS PERFECT. I CHANGE MY OIL WITH THIS PRODUCT RELIGIOUSLY EVERY (3 MONTHS). FAR CHEAPER TO SPEND ($30.00) EVERY (3 MONTHS) THAN REBUILD YOUR ENGINE! THIS STUFF IS AWESOME FOR OLDER ENGINES!

AWESOME OIL

Been using mobil one synthetic oil for 40 years. Best synthetic oil out there and when they have the rebates, it's a great deal.

Mobil one Synthetic oil

[This review was collected as part of a promotion.] Always a great product, have used for years. Only gave 4 stars to it leaking some as mentioned earlier.

This is a blend of group III and group IV oils.  While it is a good, overall synthetic, it is not as good as alternatives that are full group IV true synthetics.

Not as good as alternatives

At least one of the items had been opened and wasn't sealed and the oil appeared to be much darker than the same oil I've purchased before :-(
