I rebuild bikes.. And this IS the stuff! Shadow's, Intruder's, Gixxers.. doesn't really matter. The bike will shift smoother, start easier, and run quieter. Just remember.. if you go synthetic, you gotta stay synthetic. ALWAYS change the filter when you change the oil.

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've used this in my Duramax pickup since 2004. I has helped keep my engine like new. I bought a V-4 Honda motorcycle four years ago and was pleased that the ST Owners forum recommended this same oil. After 50,000 miles in less than four years my ST performs like new.

Did some research, and found out that the T6 15-W40 oil has all the necessary certifications to be used in a motorcycle, even with a wet clutch. This oil is a quarter as expensive as the Castrol or Motul oils I was running before, and at least around 2k miles in, it seems to run just as well.

I started using this oil about 3 or 4 years ago in my 2006 Kawasaki 1600 Nomad as an alternative to the high priced Honda factory oil I was getting. This stuff is great, my clutch doesn't "hang up" anymore and actually shifted more smoothly right away when I first switched over. Yes it is Jaso rated for wet clutches!!

I use T6 5W-40 for all non catalyst engines from small engines to tractors and older gas trucks. I live in ND where the temps range from -30F to 100F in a season and this oil has performed excellent in both gas and diesels. The only thing that sucks is the ZDDP will smoke o2 sensors in newer vehicles so I quit using it there. Nice to have one oil do the job of three.

Used T6 in my 2007 FZ1 since I bought it used about four years ago. I rev this bike to the Max, never had a single engine problem, doesn't run hot, uses zero oil in between changes. I understand that it shears easily in a wet clutch situation (as do many oils) so I change it as I reach about 1k or 1.2k miles that way the engine always gets fresh oil. It's cheap and not that hard to change oil and filter. I only ride for fun so I change it maybe a couple of times a year.

This Shell Rotella T6 5w-40 Synthetic engine oil is both a quality product and very affordable for 4-stroke motorcycles which use 10w-40 conventional engine oil. After the auto supply store where I had bought conventional oil for my motorcycle raised the price to an outlandish level I found this very reasonably priced Shell Rotella synthetic oil at Walmart, and it is has the JASO-MA rating which indicates that it is also formulated for wet clutch motorcycles. I have been using it in my Kawasaki Vulcan 900 Classic LT for some time with zero oil consumption, and on my oil pressure gauge it registers according to the Kawasaki shop manual spec regarding pressure.

Love this oil in my ATV. Turns smooth as silk. Some may question, why it's a diesel oil. Why you putting that in a quad. Trust me its JASO certified. Which is why I use it. Check it out and read up on all the reviews. YouTube has alot on this oil for motorcycle oil. I highly recommend

Rotella t is one of the best diesel oils ever. And Walmart has the best prices on it AND they will deliver it to the house? Critical for someone like me who has disabilities. Walmart's delivery service is more than a convenience, it is a lifeline for those with disabilities.
