AMSOIL MCV 20w50

S) that has had a positive experience with AMSOIL Synthetic Motorcycle Oil 20w50. As we have documented before in the Motorcycle Oil Testing article,

AMSOIL manufactures the highest quality products available. Though vigorous testing, AMSOIL motorcycle oil’s outperform the competition by offering high wear protection, and ultimate performance.

You’ll notice by my signature below that I am an employee of Chevron Global lubricants division. I originally worked for Amoco at the R&D facility before moving into marketing, and while in that role, Chevron bought our lubricants business right after I moved to Florida.

All in all, I have more than 34 years of experience in fuels and lubricants testing, development and tech service support.

I own three motorcycles that I either drive on the street or race. What I wanted to share with you today is my experience with my drag bike.

It is a Yamaha Roadstar Warrior. Originally built as a power cruiser, but now it is stretched, slammed and built to run on E-85 fuel and nitrous oxide. I have taken this bike from a fun street cruiser to a beast that wants to jump out from under me every time I snap the throttle.

The engine is putting out more than three times the horsepower it was originally built with, and with the highly oxygenated fuel, nitrous and severe use, I have been battling cylinder and piston ring distress for a couple of years. Essentially, whenever I did a teardown, there was evidence of streaking of the Nikasil-lined aluminum cylinder, essentially a scuffing situation that is aggravated by the high cylinder pressures and fuel dilution.

Since Chevron does not make motorcycle oils, I have had to try many of the “other” different motor oils, all synthetic. To make a long story short, I should have read your white paper on motorcycle oil testing. It would have saved me at least three premature teardowns. Bottom line – the AMSOIL 20W-50 Synthetic Motorcycle Oil has completely solved my problems. I have been running it for over a year now, and compression and leakdown have stayed at the exact level as when the engine was freshly rebuilt. This weekend, I tore down the top end to try a new piston ring combination, and the cylinders had absolutely NO sign of streaking or other wear-related distress.

Also, all other clearances, including valve lash and valve guide and bearing, have stayed the same. This is truly remarkable.

In my training endeavors, I run into a lot of end users who are high performance junkies just like me. I have no problem sharing my experience with the AMSOIL products. In fact, just last month, I gave some lubricant training to 187 instructors at the UTI technical school in Orlando. I made it very clear that I was a big fan of yours. Thank you so much for the great product.
