How Often Should You Change Your Oil?

Here is what I use to determine how often to change my oil.

Very sensible. Always lean to more frequently if unsure. This is important for guys that run synthetic because it lasts longer. Yes it synthetic has a higher shear factor but it gets contaminated just the same as mineral thus needing to change it just as often normally.

I hope it works out that I can bring you my 500exc motor some day after I've put multiple continents worth of mileage on it. You know, for scientifical research 🛠️🔬
