I am currently running bel ray 10-40 non synthetic in the bike and it runs fine. I got 1100 miles on it and was thinking about switching to synthetic at 2000. Is this a good idea? or what miles is good to change? and should i go to semi synthetic and then synthetic or just throw some amsoil full synthetic in it?
thanks

 

Some people say use a blend...Some say go straight full switch either way its all good...if you are not comfortable when you do the change throw some Seafoam in there with it you can switch anytime i just used mobil 1 full syn when i hit 12k which was the first oil change i have done myself...

 

I just put in the Honda full synthetic (gold bottle) at 9k last weekend for the first time and I don't notice any difference in how it shifts. =/ I shoulda just stayed with the cheap Honda oil.

 

I just changed to Mobil One 10-40w synthetic blend about three weeks ago. Before that was Penzoil standard 10-40w. This is only my second oil change (did both myself) and I have about 4500 miles on the bike so far. The bike seems to respond better with the synthetic blend. I was thinking about going full synthetic on the next change, but if there's no difference, then I'll just save money by sticking to the synthetic blend.

 

Working on cars, I'm not a big fan of synthetics unless you switch to synthetic at a low mileage and stick with it... Switching to synthetic at a high mileage just helps lubricate seals that have gunked up and dried which causes leaks......Also todays conventional oil have to meet a pretty high standard...Read the classification on the back of the bottleand make sure it meets your bikes OEM specs.
Everyone here will probably disagree with me on this one, but if you really wanted to go synthetic I would go with a semi-synthetic...Full synthetics, IMO, are a marketing ploy and a big rip-off.. You get all the lubricating charastics of a synthetic oil in a semi-synthetic without having to bend over to far...
I.E....Synthetic is said to bebetter for your bike when you first start it when all the oil has drained to the oil pan..(It's slightly better for your cam bearings, etc during cold starts)

The only other advantage of a full synthetic to a semi-synthetic that I can think of is that the oil won't break down as quickly....Again, if you buy a conventional oil or semi-synthetic oil that meets or exceeds your bikes classification, it will last plenty long...Especially if you change your oil when you're suppossed too.

 

I switched at 3K.
