[QUOTE="john3_16, post: 938457, member: 53961"] The junk oil I was referring to was Honda GN4, Golden Spectro, Repsol, and there are a few others...Some of these oils are $8 per quart and lose their viscosity faster than ice cream at room temperature (slight exaggeration)...Like I said, consistant UOA's with 200ppm of iron and AL with these motorcycle specific oils verses 10ppm repectively with Mobile 1 15W50 car oil in the same bike and same conditions on a consistant basis is hardly just an opinion....Amsoil is a good oil and IMHO it is a little more expensive and more difficult to obtain for the average joe (Wallyworld). Most petroleum based moto specific oils compared to HD diesel oils approved for gasoline engines contain just as much if not more of the same antiwear aditives with no moly...My only point being that some products sold as a car oil have almost identical additive packages (HD oils often have more of the same antiwear additives) as the cycle specific oils at a much cheaper price. I'm just trying to share the info so we can all save some money and avoid being ripped off by overly optimistic cycle specific oil labels...I've seen the VOA's (virgin oil analysis i.e shows what is contained in the oil before it is used) of Mobil 1 15W50 (car oil) and Mobile's motorcycle specific oil called MX4T and 20W50 Vtwin oil and it is almost identical except for they cost $2.50 or more per quart. Why pay more for an oil that virtually identical except for packaging ? Like I said...Amsoil is an excellent oil and this is from seeing the UOA's from average joes that aren't dealers...But how much different are amsoils car and motorcycle oils? Amsoils 15W40 car oil has more antiwear additives than their moto specific oils...Compare and see for yourself. Here are some VOA's to consider if anyone is interested...Pay special attention to the calcium, phosphorous, and zinc contents. The first link is amsoils moto specific oil that sells for about $8.95 per quart and the second link is a whole bunch of VOA's with Amsoils car oils at the top...Compare and save $$. If you're going to go with Amsoil, why not just go with the cheaper car oil ?

The guy I know that works for an independent engine test lab is only interested in getting the best oil at the best price to protect the engine in his $11,000 motorcycle so I can hardly imagine him being swayed by labels claiming more protection when he has unlimited access to hundreds of thousands of dollars worth of the latest test equipment.
