Review of Mobil 1 (45000-6PK) 5W-30 High Mileage Motor Oil - 1 Quart Bottle

Customer Ratings:

I used the Mobil 1 High Milage oil in a 2003 Dodge Dakota with the last of the 5.9 Liter engines. I noteiced that around 80,000 miles that on steep inclines the engine would rattle a bit in the passing gear. After about 2 weeks of the High Milage oil in the system the "rattling" has stopped.

Quite satisfied.

Mobil 1 is the standard by which all other synthetic oils are judged. Better price at Costco with a coupon, but a larger choice at Amazon fits every need and is cheaper than the big box stores.

This is the best high mileage synthenic oil you can get. Using this in my Lexus GS400 with 135,000 miles and going strong. Prevents leaks that mosts standard synthetic oils will cause in older cars.

The last thing I want to do is start a never ending "Oil thread debate" over 2-cycle oil brands on Amazon,

I do want to explain why I chose to switch to Bel-ray H1R for my Outdoor power equipment. Keep in mind that Not all 2 stroke engines are operated in the same way so it shouldn't be "Assumed" that a paticular oil will always act in the same predictable manor for all different applications. For example: Most pro-saws are

operated @ "Wide open Throttle" while in the cut, and usually idling when not in the cut. This is much different than say a dirt bike where throttle is continuously varying depending on what the rider needs at the time. Both are air-cooled 2-strokes, but operated differently.

I primarily use 2 stroke oil for Outdoor Power Equipment so that's the application I'll speak to in this review.

I've tried several synthetic 2-cycle oils, But I switched to Bel-Ray H1R on the advice of a well-respected/professional chainsaw

engine builder who "Ports" saws for even Higher Performance than OEM.

He services these engines everyday for a living, He modify's intake and exhaust ports, increases compression, advances timing, Etc.

Basically he "Hod rods" them so to speak and returns them to the customer. I trust his judgment as he has tremendous experience

in this field and see's the effects of various oils have on bearings, cylinder wall's etc on a daily basis.

He also is not a "Dealer" for any specific oil, and has only the end-user interests and ultimately his own reputation for durability in mind-(unbiased opinion.)

Many of his customers want the added performance porting offers, but also rely on their saws to put food on the table, and need them to be reliable daily for many years to come.

Bel-Ray H1R is his oil of choice/recommendation in high performance air-cooled applications such as O.P.E.

Two of the Saws that I sent him had seen a lot of use over many years-(Husqvarna 346xp/372xp). I had used a well known/respected synthetic 2 cycle

oil in for many years. When he got into the saws he found although they had minimal wear, and a nice shene of oil on the piston skirt/bearings,

there was however extensive "Hard-Crusted" carbon build-up on the piston top, the combustion chamber and the muffler that he had a hard time scraping off in preparation for the port work I requested. He also indicated that this had not yet caused a problem, but was heading in that direction. I told him I always carefully mix @ 50:1 using premium pump gas as per the OEM manual. Also the saws were tuned correctly and ran great prior to him porting them.

Using H1R will keep things clean, and well lubricated for long term/high performance use.

The only reason I rated it 4 stars was I wish it were a different color, as it hard to tell the difference from straight gas with the color of it being orange/red.

(It's a good idea to label your containers Date/ratio/etc!).

Also Here is a Link to a study that was done to compare the effects of different

high performance synthetic 2-cycle oils in a stress test should you want to read up further:

Great oil for my car and the really hot climate. Used to be able to get this in the gallon containers but that went away over a year ago and hasn't returned. Oil well, maybe next year.

You can pay more, but you can't buy better. As good as the $20 a quart stuff. Have been using for years, the last 12 yrs I have ran this in Harley Davidson Twin Cam motors where oil temps routinely reach 250 degs. Zero failures

I use this in a hot rod with 550hp and works great. The viscosity stays the same whether hot or cold and that is the big advantage with synthetic motor oil. It also contains more of the additives needed by high performance engines for long camshaft life. Also with the slipperyness of synthetic motor oil, there is a performance gain. I have been using Mobil 1 for years in all my cars and trucks.

Full synthetic motor oil is the best thing since sliced bread for small air cooled engines, such as lawnmowers and snowblowers. My five star rating is based on that application. In my opinion, full synthetic motor oil is very expensive overkill in the family car, with the exception of engines that were designed from the ground up to require it. I would give Mobil One only two stars for automotive use due to the excessive cost.

Air cooled engines have very poor temperature control. The hot spots get so hot that conventional oil burns to fine particles of carbon. You can see conventional oil turn to a dark brown color after only a few runs of the engine after an oil change. That's not dirt getting into the engine; it's immediate thermal breakdown of the oil.

The typical air cooled engine only takes 0.75 quart for an oil change, so the price premium over conventional oil is trivial. You should change the oil every year, but if you don't, you will notice that the oil stays clean looking for several seasons.

The viscosity grade of Mobil One 15W-50 is perfect for lawnmowers. For a snowblower, consider 0W-40 instead.

It's a different story for the water cooled engines in cars. Tight thermal control has been the name of the game ever since emission regulations were enacted in 1968, with every new generation of engines being better than the last. Cold spots produce CO and unburned hydrocarbons, and hot spots produce nitrogen oxides. Both have been eliminated. Remember that full synthetics were invented for use on the Alaska pipe line project. Not many of us in the lower 48 will ever have to start our cars at -50 degrees Fahrenheit.
