I usually don't use Lucas Pure Synthetic Oil Stabilizer. I learned something new from this experiment.
My Yamaha WR250R has very high demands on it's motor oil so I have been trying different things to get more use out of it. It goes from 10w-40 to 5w-20 in just 1000 miles and at that point, that's just terrible protection. I've been trying to find oil which supports both my wet clutch and the engine to a greater distance.
In fact, watching this video, makes me think that would I should have tried is Lucas's oil Heavy Duty Oil Stabilizer which wasn't for medium weight synethetic oils like the more modern synthetic is. I noticed on the shelf now is actually an even thinner Lucas Oil Stabilizer, which is designed for modern engines. Clearly straight 40 weight in any quantity would be really hard on VVT type systems which requires oil to pressurize through much tinier openings than what oil was asked to do in the past. Thus, all the new thinner oils in modern cars.
A thin oil in my Yamaha would be a disaster. See my related video where I learned what synthetic oils, even JASO MA & MA2 approved for wet clutch oils does to my Yamaha: • Yamalube Oil vs. Castr...
So, at just 1 oz. of the synthetic oil stabilizer, I'm getting marginal increases of viscosity. But I can't do more...trying 2 oz. made my clutch slip so bad I was afraid 10 minutes into my commute, that I wouldn't be getting to my job. It was about 2nds of my life, but it was a very high stress, thinking, my experiments have cost me being on time for work!
This information should be very similar from for 2008 to 2019 Yamaha WR250R motorcycles, but the engine was changed a bit in about 2015 so earlier models may be effected a bit differently. In this video, other than the additive, I've only shown JASO MA and MA2 oils. This means that they are approved for wet clutch use.
In another year of owning this motorcycle, I'm thinking this brand new motorcycle just never had strong springs on it's clutch. I'm going to upgrade it when I change my clutch and see if my life gets easier, I don't have to change the oil every 2 weeks of riding, and I can just run synthetics which keep their viscosity up and protect the engine at the maximum for the longest.
In the use of Castrol 10w-40 I was not getting more than 1k miles of an oil change interval or OCI. That's SO little. That's why I considered oil additives. That and I use Lucas Pure Syntheric Oil Stabilizer so little that it's kind of just sitting around.
In the search for the best oil for my motorcycle, I'm trying my hand at Sheel 15w-40 next. My Yamaha WR250R calls for 10w-40, so I mixed it down a bit, but I'm seriously starting to think to have more range, I just need to start with something higher. Maybe even 15w-50.
