Does anyone on this board use Shell Rottela T full synthetic in there FJR
Not yet in my fjr, but for the last 15 years it is all that i have used in my OTR trucks. Not one bottom end issue or bearing failure and the inside of the motors is always spotless. I have long debated with myself on the merits of synthetic oil vs mineral based. For myself just good oil and filters with regular service intervals always seems to work the best.Does anyone on this board use Shell Rottela T full synthetic in there FJR
+1Last few oil changes I've switched to the Rotella dino oil 15W-40.
IRBR, I understand what you are saying. However I don't use it because it's cheap to purchase, I use it because for me it works. Just one other note, I frequent a pontiac board with some very smart guys on it. A lot of them race and I mean some of the fastest sanctioned cars in the country. You would be surprised how many of them swear by rotella, and they don't buy it because you can get it at walmart. StanA couple of years ago, and for my own benefit, I did a significant amount of technical research on oils. The issue was more complicated than I had imagined.
I learned a few memorable things:
> Pure synthetics have some difficulty suspending additives. Dino oils or semi-synthetics do a better job of homogeneous additive suspension.
> There are 5 classifications of oil. Class 3 is actually dino oil that has been modified to mimic a pure synthetic class 4 or 5 oil and they do a pretty good job of this.
> The oil itself doesn't wear out. What wears out is the long molecules added to oil to make it multi-viscosity. What damages them is the "munching" they get in the transmission and the oil pump.
> For every thing done or added to an oil to improve one characteristic, there is a loss or trade-off in another.
> No oil is perfect and there is no one best oil; they are all compromised to achieve certain performance characteristics.
> Lubrication engineers know a LOT more about lubrication and oil than I ever will.
I've seen threads about Rotella for years. Empirically, it appears to be a great oil at an affordable price. But I still marvel at the fact that people are willing to risk their multi-thousand dollar engines and transmissions to experiment with lubricants that save them a few dollars per oil change.
Using Rotella in your bikes is probably fine but I won't do it. The people that designed our bikes' engines and transmissions know a lot more than I do and they spec'ed the lubricants. I do what they say and use expensive, high-quality, JASO spec oils.
My 2 cents,

HEY I changed it today Rottella T 15W40W 8.88 per gallon on sale ay walmart. so far so good. :yahoo:I use Rotella Synthetic in the FJR for one main reason. That oil works well in my diesel truck, my cars, and the lawn mowers. I was sick of having different types of oil for different things. Does make for a notchy transmission though. The STP sounds like a good idea. I think I'll try that.
