Which Engine Oil

[celticbiker]

No argument celtic , just my opinion based on approx 500,000 miles over 8 bikes all owned from new and fed nothing but gtx. I've never had a single engine problem. Two I still own , a 78 z1000 showing 56k and a 97 4tx showing 99k (never had the cam cover off). My only s/hand bike being a recent bought 24k 4tx. The manufacturers can package oil as they please but they have to display the spec and it's basically 50 year old spec. It has to be. Forums are for sharing opinions and information. This one seems incredibly civil to me.

For a change it's nice to see the opinion of someone who has real world experience and hands on testing, rather than some oik who says he's "had sunflower oil in his bike for the past five years without any problems and he's done nearly 1000 miles".

Opinions from people such as yourself are always worth considering.
