bike is a 2008 Suzuki Boulevard C90...Perfect. Great clutch feel and shift effort is nil. No ticking in the engine. and the cost is amazing. And on my 2016 Ram EcoDiesel, the factory oil was running almost one hundred dollars (10.5Qt required), now that Ram said "OK" to Rotella, im down around 60US! Awesome

I ran this oil in my Toyota Corolla for 10,000 miles, and had it tested by Blackstone Labs, and the amount of wear in those 10,000 miles was so low that it almost could not be measured, and Blackstone said that the oil was still pristine, and that I could easily run it for another 5,000 miles.

I have been using Rotella in my 1997 Ford F-250 since I bought the truck new in 1997. I switched from T-4 to T-6 a few years ago and only use about 4 oz of oil between changes every 5000 miles. The truck starts much easier in cold weather. I have 178,000 miles on the truck and I have no oil leaks.

I use this Rotella T6 in all my cars with synthetic requirement for oil. Its low weight and high viscosity - good stuff. Holds up well in my 350HP turbo application and also lasts the 7,500mi interval for my non-turbo car. I have even started trying in my motorcycle and so far seems good.

I have been running shell oil since I bought my duramax in 2002, the truck has been used for construction in northern Alberta in the oilfield it’s entire life. Big trailers, -30C morning starts, working lots of hours , Shell’s fluids have never let me down. The truck has 800000 km- 12000 engine hours on it and the engine runs as good as it did the day I drove it off the lot. Doesn’t use any oil at all from oil change to oil change. I Switched to t6 at 400000km and run the 5w40 year round. I change oil every 5-6000 km. If your looking for the best fluids to run in your diesel pick up this is it.

I've been using T6, 5w-40 in my Terex diesel mini-excavator for four years. Cool runner and easy starts in cold weather. No engine problems or abnormal noises. Price is good with the rebate program. As an aside, I'm wondering if the motorcycle guys may have a "wet" clutch which normally requires a NON-synthetic oil.

I use Rotella T6 in almost everything I own and have owned in the past. Its in my Toyota 4Runner, Its in my sons Kawasaki KX65 two-stroke, Its in my my Honda CRF450R, and also my CRF150R, Its in my lawnmower, and Its in my 4-stroke weed eater. It also does not cause any clutch slippage in wet clutches. I don't use it in my Tundra and Honda Odyssey because its not the right viscosity but I wish I could. I've used T6 exclusively for years in all my engines and never had a problem or any signs of wear.

I been running this in all my cars and trucks, ATV for many years. My 2007 Chevy Cobalt I drive the most and it has 160,000 miles and I been running this oil since 60,000 miles, starts great in Minnesota winters and I never replaced anything except brakes

I did experience some slippage of gear / I guess my bike got spoiled by $20 -$35 a quart.. For 1/4 the price - I now can afford Shell Premium Gas prices... I use to drive 20+ miles just to save a $1 a gallon for gas. (Also, enjoyed the ride to finding these unknown -gas stations, but now that more bikers are getting killed from distracted drives - I stay off the road during heavy traffic)

I have been using this oil in my 1998 Honda F6 Valkyrie Tourer for 6 years now, and have had no issues with clutch operation. Even at full throttle with the big 6 cylinder engine, no clutch slippage. Also, the notorious Valkyrie top gear whine was a lot quieter immediately after the first oil change. It's also priced a lot cheaper than the competing oils, a nice added bonus. I don't hesitate to change the oil when I should, when the price is about half of other high end or OEM oils. It's available at many local retailers, so, it's easy to obtain. I wish it was available in other weights like 5W20. I would use it my 2010 F150 5.4L if I could, because it's really not that much more expensive than conventional oil.
