choosing trans oil for my bike for the first time. any recommendations on great oil? should I use syn or petrol based?
Agreed. I use the 5W40 Syn as it is just a bit more than most other 10W40's. When I am using SYN T6 I change my oil and filter at twice the "DASH's" change oil light set at 3600 miles so every 7200 miles.Nothing wrong with the Rotella T6 Synthetic. I however use Rotella T 15W-40 non synthetic. I change the oil at 4,000 miles intervals and can't see the need for synthetic unless I'm going to go to much longer change intervals.
Also we use Rotella Triple Protection 15W-40 in motor and trans. and change EMGO filter each time also, change oil + filter every 3500 - 4000 mile.Nothing wrong with the Rotella T6 Synthetic. I however use Rotella T 15W-40 non synthetic. I change the oil at 4,000 miles intervals and can't see the need for synthetic unless I'm going to go to much longer change intervals.
Rotella T Triple Protection 15W-40 non-synth is still made and still has the JASO MA rating printed on the label.Rotella used to make (and still may) Rotella T Triple Protection 15-40 non-synth. It was also rated JASO MA.
I found it interesting that Shell told him he could blend T6 5W40 and 15W40 Dino to make 10W40 semi synthetic.Re: Shell Rotella 15w40 (reg/synth)
FYI...The Rotella "Triple Protection" dino and the T6, synthetic oil are both JASO MA (stands for motorcycle application) approved. The Rotella T3 dino and T5 blend are NOT JASO MA approved. To be MA approved it has to be safe for a wet clutch. I contacted Shell and they told me the T5 is NOT a blend of the Triple protection and the T6, and is not JASO MA. He did say you could blend the "Triple Protection" and the T6 at a 50/50 mix and end up with what would be a 10W40 semi synthetic that would be JASO MA. I had always thought the T3 was the same as the "Triple Protection" but it turns out they are not.
