Amsoil MCF, MCV, and Mobil 1 Racing 4T and V-Twin consistently turn in the best results. When it was included, HP4 did OK, overall. It did fall out of grade during the viscosity shear test I consider so important, but it took longer than most by far. Motul oils do well, as do the Torco and Spectro MC oils.

Just be sure you don't use the MB version of HP4 (you knew that already).

So how does Bel-Ray thumper rate in all this?

The only Bel-Ray oils I've seen come through were EXS and V-Twin. V-Twin was barely a 20w-50 to start with, and dropped into the 40 range during the first of 4 test cycles. EXS lost viscosity in each cycle, but remained a 40 weight the entire time. It generally did OK.

I'll just tell you that I wouldn't use it and let you make that decision.

Correct.

If I had it, I'd use it and save a few $$ this time around - or put it in something else. No sense just tossing the stuff. Not going to hurt anything if you change to a different brand later. Your call.

Just get a good, respected brand synthetic oil you like and stick with it. Remember to change it often.:thumbsup:

For oil filters, I'd probably buy a Scotts Performance stainless steel oil filter, EOYZF. You can easily clean it, and its reuseable.

Anyone sell Amsoil in your town? Here in Sandy, we've got a retired guy I go to church with that has a rack full of different Amsoil products at a convenience store. It's probably not the cheapest way to go, but he's always got MCF there...... :thumbsup:

It sounds like you don't like WalMart? :thumbsup:

It's not the one in Pendleton, by any chance, is it? That one is particularly craptastic......

Buy directly from Amsoil at Amsoil.com. If you use more than say 12 quarts in a year, you'll be money ahead of buying it out of a shop if you sign up as a preferred customer, even with the $20 fee and the shipping. Then you won't need to go farther than your front porch.

If you HAVE to use one from Wally World, look for Mobil 1 Racing 4T motorcycle oil. If they don't have it, Mobil 1 Extended Performance has the best chance of staying in grade, with Mobil 1 Truck and SUV being a next choice.

I order Amsoil this way and it haves money as well as hassle. I believe, being a preferred customer, I can buy one quart at almost half the price of the local dealerships, and there's even more savings to be made buying in bulk.

If that's true, your local dealers are running the price up big time. If you go to Amsoil.com and look up MCF without logging into your account, you can see what MSRP is. You're saving around 22-25% off retail.

Is it not true that synthetics only matter for long duration use meaning that there is no benefit to a synthetic if you change your oil often? Often meaning every couple hours. OBTW I use yamalube semi-syn with a freshly cleaned scotts stainless filter, then the next change leave the filter in and use the regular yamalube. Gray does this sound reasonable? With all the 3 YZ450's I've had I typically change the oil on a 4-6hr basis - I race and ride them hard, never had issues, but that doesn't mean anything really since I didn't put even 100 hours on them. I had read advice in a magazine from one of the Yamaha techs that every 4 hours is all you need. I'm now taking shelter!

Why wouldn't you use the same oil every time you change the oil?

75% of the wear in an engine happens in the first 5 minutes. Synthetic oils do a much better job of protecting an engine during the crucial warm up period. Therefore, if you want your motor to hold up, only use a quality synthetic oil. Fooling around with cheap non-synthetic oil is just a bad idea -- unless you like replacing engine parts (rather than oil) frequently.

75% of the wear in an engine happens in the first 5 minutes. Synthetic oils do a much better job of protecting an engine during the crucial warm up period.

That's a bit of a two-part myth there, at least partially so.

For one thing, the 75% quote is used to describe normal wear on an automobile engine, and 75% is a bit of a conditional exaggeration. Certainly, cold staring is a problem to be dealt with, but the wear that occurs during startup is not 3 times that which occurs in, for example, the top 8mm of the cylinder during high RPM operation under power in a typical MX four-stroke. Also, the oil has to have the ability to prevent failures under extreme conditions that would not be considered normal wear events.

Secondly, the cold start protection comes from the anti-wear additive package, which can be the same regardless of the base stock the oil is made from, and from using multi-grade oils such as 10w-40's that are thin enough at low temperatures to flow freely and quickly through the oiling system. Multi-grades are also available in both synthetic and natural petroleum based oils.

Synthetics, per se, are no better at cold start protection than petro oils unless you specify Group V esters, which do have the advantage of polar behavior. That is to say that the oil film has a tendency to be attracted to and cling onto metal parts to a greater degree than other oils, so they tend not to drain off completely over time. In other premium oils, the anti-wear additives pretty much take care of this without relying on polarity, but it's a nice feature, nevertheless.
