A study of motorcycle oils

[Bonez]

I'll keep buying mine for around $14 for 4 ltr and change it, as well as the filter, every 3000-5000kms thank you.

I have no experience with bikes and enough I guess to throw in my 2c when it comes to engines and oils etc.

It's my understanding that certain oils display different properties. For instance while something like Castrol Edge might be a synthetic oil that provides better lubrication for the engine it also lacks the heat dissipation properties provided by a semi-synthetic (protec) or mineral oil.

Again my understanding is that while your owners manual will provide the correct viscosity levels that you'll be requiring for your bike they often don't specify which type of oil to use.

Basically my point is: Some oils may provide a show a better viscosity consistency (or whatever you might want to call it) only because the oil isn't removing the heat from other parts of the engine as efficiently as others might, and while they may display an increase in horsepower it may be hiding an increased amount of wear due to heat or lesser protection
