cabby Posted February 25, 2011 Report Share Posted February 25, 2011 I have always used fully synthetic oil in my trials bike, however, I have just read elsewhere that one of the top riders in Britain uses semi and said fully is a big no no ? Anyone care to tell me what the benefits are of semi against fully or vice versa and should I change to semi ? 1 Quote Link to comment Share on other sites More sharing options...

paul w Posted February 25, 2011 Report Share Posted February 25, 2011 just to add confusion, i use this stuff, its a synthetic blend, whatever that is. i have used for years, and whenever i have stripped engines that have used this it leave a nice coating on all the surfaces. cheers paul http://www.feridax.com/product/0264571/3/3660/pj1_oils_632.html Quote Link to comment Share on other sites More sharing options...

Perhaps the Californians should tell others and not keep this big secret to themselves ! Quote Link to comment Share on other sites More sharing options...
sherco29 Posted February 25, 2011 Report Share Posted February 25, 2011 Everything is known to cause cancer in California. Pay no attention to that! Quote Link to comment Share on other sites More sharing options...
feetupfun Posted February 26, 2011 Report Share Posted February 26, 2011 Full synthetic gives the lesser amount of smoke, lubricates best under extreme conditions (pressure and temperature), causes less carbon build-up in the combustion zone, tends to create less ring gumming issues Semi synthetic is not quite as good as synthetic in all those areas, but protects the steel items inside the motor (conrod bearings especially) from corrosion better than synthetic while the bike is not being ridden.

Anyone care to tell me what the benefits are of semi against fully or vice versa and should I change to semi ? I think he is full of crap, and trying to push off something. He needs to stick with riding, not oil engineering. Flip side to all this seems to me that the high quality simi blends work just as well in a trials bike, and in most cases the less you use the better off you are whisst putting about. The type of running to occasionally blow them out is far more important than this debate. 1 Quote Link to comment Share on other sites More sharing options...
b40rt Posted February 26, 2011 Report Share Posted February 26, 2011 Fully synthetic is not recommended on new engines as it is to good and the rings do not bed in properly. Quote Link to comment Share on other sites More sharing options...

He needs to stick with riding, not oil engineering. he may well be full of crap, but he certainly wasn't pushing anything on me, just his take on things, and given he's British Expert A champion 2010, reckon listening to his opinion/advice may well carry more salt that any tom dick or Harry over the tinternet granted I did ask As for oil engineering, you gotta laugh at that comment, I ask a question, get a few various answers, and you tell him to stick to riding and not oil engineering Quote Link to comment Share on other sites More sharing options...

Did he tell you, or did you read it? As you say he wasn’t pushing anything on you, but you said you read it Edited February 27, 2011 by Monty_Jon Quote Link to comment Share on other sites More sharing options...
cabby Posted February 27, 2011 Author Report Share Posted February 27, 2011 He is Gary Mac. I read it initially. I then asked him personally. He never, at any time mentioned any type of oil, he wasn't pushing anything, he's a jiner, no an oil salesman. Any further questions ?

What have you been drinking? What have you been drinking more like, have another read of your post My comment was in relation to copemech alluding possibly to him pushing something, saying he uses semi instead of fully is hardly pushing a product is it Edited February 27, 2011 by Thedbf Quote Link to comment Share on other sites More sharing options...
