Golden Spectro to Mobil??

[Hot4Teacher]

I have a '99 yz400 and have been using 20w-50 Synthetic Golden Spectro in it. Also, because thats what was being ran in it when I bought it. I have read some good things about Mobil 15w-50 that some of the guys are running. Should there be a problem switching? The Golden Spectro here is really tough to find and when I do it is around $7.00 a quart. The Mobil is found almost anywhere. Thanks for any help.

There shouldn't be any problems running that oil.
Rich Rohrich has a GREAT :thumb: article about it...

Thanks sb I remember reading that but I forgot exactly where. I was just worried about changing brands do to the base compounds hell I don't know just don't want to damage the lady. My buddy has been thinking about switching as well (he has a '01 426). It's just sometimes when we go on 3 to 4 day rides sometimes we need oil for a change or two. It gets expensive to take 6 to 7 qts. of Spectro. If you can get the same protection with a fraction of the cost why not? Thanks for the thread.
