Lol I've heard of people mixing oil while changing their oil like a little Lucas synthetic and a little Castrol 10w 40 and a little of some other kind. Well this was my friend that mixed these, it actually seem to make his ride run better lol with no problems later on.

Default help wth my oil

for years i have followed the lead of a Castrol factory rep - use Castrol Syntec Blend and alternate every other oil change with the next best Q-State. Why? dont know but at 3k-5k oil change oil the oil still looks good.

Yeah you can mix oils to you heart's content, no problems. The only one I can think of is if you have a LOT of miles and you're contenplating switching to synthetic.

The only issue is with mixing the additives that are in the oil. Its OK to switch, just don't do it all the time.

My personal experienc from years in the field of "Fluid Power" (Hydraulics) is... No Never Mix Two Different Oils! Specially gear oil!!! Nothing may ever happen but you are rolling the dice each time you do mix oils.

If I have a need to use a different oil, all the old or other stuff is drained!

Different manufactures use different detergents, anti-foaming chemicals as well as other physical/chemical make-ups (properties) and they are not always as compatible as you may think.

The weight of the oil dosen't matter, some people mix different weights depending on the time of year. What matters is keeping the brand/manufacture and the type (synthentic or blend) of oil the same.

My advice, Don't!

It is ok to mix engine oils as long as it is the same weight. This is not true for gear oil and tranny fluid. Mixing these oils can lead to damage to the clutch and slipping.
