Is synthetic oil any good in a Quad ? ( 2000 450ES ) ?? Give me the good and bad please

 

Synthetic oil is far superior to any dino oil. It is better at handling heat, will not sludge. There are countless examples of how much better it is. In fact I don't break in a new/rebuilt motor on synthetic because it is so slippery. I can't think of any bad examples. Just use a good brand, I prefer Bel Ray. I Red Line in my Buell motorbike, works great (air cooled Harley 1203cc V-twin). SO there is some heat be developed here. Oh, make sure you change the filter and grease the thing while your at it.

Here is my thought on the deal, for what its worth. I would buy NOTHING BUT a synthetic oil, for the reasons already listed.

One WARNING though, I have done a lil research on this matter and it works so good in fact, that it should not be used until the engine is entirely broken in. Not doing this, will not allow specific engine parts to seat properly

Hope this helps

Synthetic oil is by far superior to conventional type oils. However, I tend to agree with those who feel they are not worth the additional expense in terms of their ability to outperform a conventional oil, given that you change your oil at recommended intervals. Some have even called such high-priced products as "idiot oil" since it's true benefit is for those who neglect oil changes. It will continue to protect and engine from thermal breakdown after many thousands of miles.

 

Synthetic except when you are breaking your quad then don't use it

 

That seems to make sence, but in practice I found it not true. We bought 3 Fl350 Odysseys. 2 we broke in on dino oil, then switched to full synthetic. The 3rd was always full synthetic. After the first year of riding, the 3rd couldn't be touched power wise. (could be luck)

Now we use it in our Banshees and our motors go much longer between rebuilds. (could also be luck) It's great stuff!

 

I was once told that synthetic oil in a 4 stroke can cause clutch slip since it works SO well, and these are wet clutch bikes remember. I think I even experienced this with an 86 200x I once had. Of course, at the time I thought the clutch was going bad since I was using the "best oil on the market".

I now use the cheaper honda 4 cycle oil, and keep the oil changed as was suggested in an above post. I never use synthetic oil in my automobiles either.

I do however use synthetic oil in every peice of 2 cycle equipment I have, including string trimmers and chain saws. Since these machines are 2 cycle, the oil mixes better, cools better, lasts longer in storage, decreases plug fouling, and smells like a day at the races when I am weedwacking the yard
