I COMPLETLY agree!Cooker said:Jeff,
Valvoline Premium Blue Extreme is a Group III synthetic basestock. It only allowed to be called synthetic because the courts decided, in a case regarding Castrol Syntc several years ago, that Group III oils could have this right . As myself and LightmanE300 have pointed out, and I am certain amsoilman is aware of also, Group III syntetic basestocks are not in the same league as the "true" synthetic Group IV oils.
This is not to say that the PB Extreme, or anyother Group III oil for that matter, is not a good oil. Most Group III oils are offer some of the very same advantages as the true synthetic oils and FWIW - I am running a group III oil in my truck.
The Group III synthetic "issue" is pretty common knowledge in the oil industry. If you were to do a little searching around a few of the oil specific forums you would find this to be true. I brought up the issue to hopefully prevent anybody from paying too much for a group III oil. A true synthetic oil can be purchased at Wally World for $20 a gallon why would somebody want to get "duked" into buying a synthetic oil for $18 plus dollars a gallon (as the PB Extreme that I have seen is selling at) for an oil that should cost no more than $13-$14 a gallon. It is simply not that special.
Hey John, I actually work for Harley-Davidson.

Does this oil compete with Delo 400? That I can't tell you but I hope for $12. 84/gallon it's giving me something better than Delo 400. . . a tough Dino oil to beat.
In order to affordably reap the outstanding benefits base stock IV synthetics give you, you need to run extended drain intervals.
Part of my reason giving the Rotella a try is to hopefully have an oil that is superior to dino, that I can afford to change on 10k intervals. At some point I may go back to the Amsoil, because it gave me such great oil analysis numbers.

John,I work on the assembly line that would have built your motorcycle.
Vaughn MacKenzie said:Wayne I went 20,000 miles. Analysis always said OK for continued use but I thought at 20k I got my money's worth and didn't feel comfortable with going further since I didn't have bypass. I changed the Stratapore every 7-8k (at each change plus 2 times in between)

The only problem was there was only 8 qts. on the shelf. :{ Seems like the only luck I have lately is bad. :{ At least my truck is fixed and running now.![]()
