Oil debating !
Danish MC-forums frequently the question is about which type of oil is the best for your MC ? Especially owners of the old models use mineral types because the manual says that!
Mineral oil was the only choice when GW1000 / 1100 and 1200 was born. Later we have got more heat resistant and finer molecular oil types as semi or fully synthetics oils !
Here is some of the argue I have found:
Mineral oil has ashes and sulphur that can occur block ups of the oil channels and reduce lubricating. Mineral oil has lower viscosity index than Synthetic oil, which is bad
Mineral oil has a lower resistant against being too thin at high temperatures and being too thick at lowtemperatures than Synthetics oil types.
Heat of the oil is the main reason of problems with lubricating when working. Mineral is less working at a temp. above 121 ºC Synthetic at 204 ºC caused by engine friction and burning.
Mineral oil “burn of” Synthetic don’t .
Mineral oil has amounts of the so called “The VII’s” Viscocity Index Improvers” those molecules are 1000 times bigger than oil molecules. When working in the engine The VII,s buoyancy is different from the oil molecules and as a result they are now left on the bearing surfaces ! They don’t have a lubricated effect and therefore we finally have reduced this compared with a Synthetic oil which not have parts of “The VII,s”
Another bad effect of The VII’s: They are being broken down when passing the gearbox and the Clutch! That reduce the oils resistant against “High Temperature Viscocity”
The last point is: 75% of the wear of the engine comes from “Starts” When that is said it must be important that the oil runs quickly out to all the places where lubricating must be done ! How can a 20/50 mineral oil type at a outdoor temperature about 5-10 ºC do that ?
In my opinion according to the above facts,- the best choice must be a fully or semi synthetic MC oil type. All the advances of this oil compared to the mineral type talked for that !
All of you owners of GL1500 or GL1800 which oil type will you suggest/are you using? Could be interesting to hear from the vise panel out there and Jason too!
