So, I'm finishing up this thumper. The book calls for 300cc of 10 wt. in each fork. Rummaging through my supplies, I'm finding a couple of partial bottles of 5 wt, and a whole quart of 15 wt. ;D I'm thinking of mixing 300cc of 5 wt and 300cc of 15 to make 600cc of 10. Different manufacturers. Seem reasonable? It would be free.. (Guzzi content) ;D :BEER:

Or the easy way out and just use the 15 wt........

People have been mixing different weights of fork oils for years to get the viscosity and fork performance that they want. Matter of fact, I did it when I put the heavier springs and longer spacers in the Stelvio.
"Free" would be a side benefit in this case ... !

Like mixing 87 and 91 octane and hoping for 93 octane ;D

I've read not to mix viscosities. I sure I knew why at one time but I don't remember. That was long ago. :-[ I'm agreeing with Mark, just go with the 15 wt. :BEER:

Mobil 1 Synthetic ATF is approx 10wt. and works well in all the forks I've put it in.

Is this for a bike with cartridges? If so it really would not matter.
If it is the working fluid in the damper then it is a bit more critical.
I have also read that using different brands is not good (even though I have done it before). Seemed that the additives used to adjust the viscosities are different from each mfg. So, mixing two may not give you a consistent effect.

No, it's not a cartridge fork. It's made by Paioli, and is pretty stout for a putt putt that weighs 380 lbs. ;-T Maybe I should just bite the bullet and go choke gasp bb buy a bottle of 10 wt. ;D Then I can have 2 partial bottles of 5, 1 partial bottle of 10, and a full bottle of 15..

I'm sure that was in the context of oil used to lubricate an engine, with all the dynamics associated with heat, film strength, shear properties under high pressure, etc. I don't think the same applies to fork oil.

Ok, Lannis, you've convinced me. I *wanted* to be convinced anyway. ;D

I could sense that, and was trying to nudge the decision in the right direction.
I'm not an oil expert; I only play one on a Guzzi Forum. But I AM an expert on "make do and mend" on the cheap!

If the fork oil is easy to drain and refill, I'd just use the 15w. Then if it's too firm, drain it and refill with something else. If there are no drain plugs and/or it's a PITA to refill, then I'd just go buy the required weight and do it "right" the first time.

Definitely mix them, Chuck. :)

;D ;-T Me, too. I thought when I saw this poor thing, that I'd just have to put tires and battery on it and wouldn't have to spend any money other than that. Missed the $100 headlight rim/lens, and didn't know about the carb kludge. That cost another $100. 20 bux for a new petcock.. I couldn't fix it. Dang! If I'm not careful, I'll have real money in it.. ~;

;D I thought you fixed the petcock?
My $1000 Elefant is now a $2000 Elefant. Added it all up last night.

OOOH, NEVER do that! Only pain, agony, and discouragement lies down that road ....

Helps the decision making process - keep for a while and ride, or sell now.

I'll share my secret algorithm for deciding whether or not to sell something. If it's a thing that will bring $2,500 when you sell it, for example, you ask yourself "If I didn't have this thing, but had $2,500 in the bank, would I take the money out and buy this thing?" If not, sell it.

Yep, I agree, never add it up. I'd have tossed the T5 a long time ago if I added up all I spent on it.

Nope, I fixed the petcock on the Lario. This one refused my ministrations. ;D Fixed the speedo, but the tach is going to require a $50 ebay donor for parts..
Whew! I certainly hope I don't have 2K in the commie thumper when it's all said and done. ;D
