I got tired of paying $13 a quart for 'motorcycle oil' and dumped in some Mobil 1 15W-50. The bike shifts better on this stuff than on anything else I've tried, and it hasn't burned a drop in 1000 miles. I was worried about the clutch at first, but it hasn't been phased at all.
$13.00 is probably the going rate at a Dealer, have seen it as high as $17.00 and yes, at that price, they are raping you...
100% Synthetic AMSOIL from Rex or I is well below that depending on amount ordered, it can be substantial. A case of 12 is the best way to go. But even with just buying 4 qts and a filter, your cost per mile is compareable to what you have now due to the extended drain interval.
What's the take on using Diesel motor oil? Specifically, I've been using RotellaT Syn 5W-40 on my SV650 since I got it at 6500mi. It's currently at 11K, so I've only changed oil like 2-3times.
Anyway, from what I've read, these are the service specification ratings on Rotella T Synthetic
CG-4,CH-4,CI-4,CJ-4/SM (CI-4 plus)
Is any of the ratings necessarily bad or good for the bike?
I live in CA valley, so the temperatures barely get to "freezing" too often.
Rotella does claim to have an MA Rating now. But does not have all the necessary additives that are in other M/C oils such as Anti-Rust and corrossion Inhibitors, and in the case of AMSOIL, Specific Clutch Performance additives to give them a JASO MA-2, which is the highest clutch rating available and Special Anti-Wear additives for your transmission.
We take it like this... If an auto oil or diesel oil were the way to go, why would we want to mfg a Specific oil. Many M/C magazines have checked out Auto/Diesel oils compared to M/C oils and the one's that have done any homework or "Actual" testing have all said that yes, there is a difference.
Check out the link I have in the above post... Pick one of the Top 3 finishers... Don't try to cheap out....
As far as Filters... AMSOIL is unbeatable at 15 Micron, WIX is my second choice, Pure One is 3rd and Mobil-1 would bring up the 4th.
