mixing oils?

Id like to know what would happen if you mix two oils of difrent brands but they have the same grade(20w50) or mixing a synthetic oil with a conventional oil with the same grade?????:headscrat

They won't mix and it'll be funky in the engine cause the oils are different temperatures and grade.

funky? whats the worst that could happen?

Why can't you just do an oil change?:headscrat

you might wear the Bearings on your engine, I use Motul and have never had a Problem I have also heard that some Oils will make the clutch slip can Someone Verify that ???

it could cause a chemical reaction and cause the seals to swell up or cause the clutch lining to become debonded or who know what else I would not want to risk it. but its your bike.

Oh please guys, no. Modern oils are compatible with each other. As long as you're using some recent SF/SG or higher rated oil, you can mix them as much as you want and there will be no weird chemical reactions or any adverse things like that of the sort.

i had to take a class on oil for an old job, as long as there the same weight and ahve the stamp on the bottle then its all the same. Mix away

Just was wondering what would happen.....im a motorcycle technician and whenever i service some bikes theirs a half quart left over so i collect them.......Thanks fr the feed bk.:thumbup:

Yep the man is right. Motor oil companies did have uncompatable oils back in the days but so many people got screwed things had to be straightened out which resulted in them not making their oils uncompatable. Now as far as mixing I'd figure just stick to one as long as its a motorcycle oil. You can mix though. I wouldn't trust non motorcycle oils since there might be a difference between synthetics like being too slippery or some fool thing. I use the fancy motul synthetic mix that is part synthetic. Number 4 or race something. Real knowledgable right.

I agree it woln't make a lick of difference mixing oil or not. I still like full synthetic royal purple.

Welcome to the 21st century... Oils have come a long way!! Mixing synthetic and regular oils is not only ok it is usually prefered... I am a merchant marine and have worked on several ships as well working with other industrial machinery and semi-synthetic is what I have always seen. Basically you are getting the benefits of both oils while reducing the cons of each by having it mixed. ;)

so if I mix 2% milk with 1% milk, will I get sick if I drink it?:laughingr

Mixing = Ok

I guess you learn something new everyday..
