Which Engine Oil

[fixitsan]

Guys

I don't want to inflame passions on the subject of oil  but after 40 plus years of riding and 30 of driving a variety of cars and bikes

mostly on mineral oils I've never had an engine let go, seize or throw a wobbly or even start burning loads of oil until over the last 2 years when i changed the mK2  850 onto semi synthetic

since then I use about a litre every thousand miles, had the bike from new in 1999 and change the filter and oil every 2000 miles

probably coincidence!

 

Several TRX riders claim a drop in oil consumption by changing to mineral oil.

 

Im in favour of thinner oil on the grounds that oil flow is higher, therefore more surface cooling can occur.  I also find it difficult to find examples (via google) of engine failure due to using the 'wrong' oil.....although its easy to find examples of failures caused by a lack of oil.
