Mobil 20W-50 V-Twin is the worlds best 20W-50 Fully Synthetic Oil as it can handle more heat before flashing into flame than any other oil.

It's additive package is the best around.

Nothing but nothing beats this product for gasoline engines.

Anything else is #2.

Is there such thing as mobil's 20W-50 and not being the v-twin formula?

Mixguy chooses Spectro Golden 4 as his oil of choice which is a blend. While Mobil 15w-50 and Mobil v-twin 20w-50 are synthetics. I am looking for an oil to change to after my break in oil (Valvoline 40). With a pair of 540s, how would you rank the above mentioned oils for my application? I am not looking to buy the most expensive oil, unless the others will not provide the needed protection. Thanks.

I found Mobil 15w-50 at $7 and v-twin 20w-50 at $9.

I just saw the mobil 15W-50 for $28 for the 5-quart jug, and 6.46 a quart at Walmart........

It's the only fully synthetic 20w50 Mobil makes. The labeling is for marketing purposes. It is a "4-cycle engine oil".

My WallLand will take an order and get you as many 5 quart jugs as you want.

GOTCHA, i ended up going with the Mobil 15W-30 and the mobile 302 filter

I just contacted the local Wal-Mart and they have the same deal with the Mobil 1 15w-50. Not a bad price $28. Is this better to use than the Spectro Golden 4 or about the same qualities?

Spectro Platinum Fully Synthetic PAO IV is equal I would say.

Spectro Golden 4 Blend is not nearly as good as M-1.

Don't forget about these 2 strong oils:

Also look at this test. It is about motorcycle oils but still provides good info about a couple of the oils in this discussion.
