Re: The Best Possible Transmission Oil

[Jessup]

Could've been answered in one sentence: Type F auto transmission oil

Facts are more credible than marketing blurb

[sav0r]

Got any facts to back that up?

I use automatic transmission in mine, but I also do that because I'm cheap and my gearboxes don't see hard conditions. And with stiff clutch springs and in spec plates my clutch tended to slip on gearbox oils. Also, since my RD like to mark it's territory the red is easy to identify.

What is the shear strength of Type F ATF?

[bitzz]

I just want to add; If you're using gearlube be sure to use GL4 rated for the yellow metal in the trans.

Kawi triple guys recommend Supertech 80-90w gear oil dino (not synthetic) sold at Walmart.  I've been using it on my triples for years with zero problems.  Maybe not the very best but for cost/benefit it's great.

I run nothing but Lucas 80\90 in all my 2 stroke transmissions for thousands of hard street miles. I have never had an oil related failure .

I run only Bel-Ray Gearsaver

Strong enough for drag car transmissions, and giant quarry dumper truck transmissions.

For the past 5-7 years or so, I have used Rotella T4 in all my bikes.

No issues and only like $12 a gallon.

I'm sure proper gear oil is better, tho.

I'm with you Russ, I only use Bel-Ray 80w in all my streetbike builds...except in the race bikes I use 75w for the most HP I can get.
I have best R&D Motorsports race prepped trannys and when you spend $600 on this, the most expensive oil is cheap!
Ed, if you want the tranny to last, just use the belray 75W. I changed my transmission oil every 2 race weekends. (200-250 miles)
I put 3 years of hard road racing on my transmission without any failure's.

In some of our dog box and sequential race cars, all with dry clutches mind you, we have run some fancy Roush 0 weight oil. The performance is there, longevity isn't much of a concern as we operate about 20% under maximum loading and stacks are replaced at the first sign of depredation. I assume it would perform well in an RD as well. I think the ultimate oil is going to be highly dependent on what you are trying to achieve.

Hi Chuck, I think you know the "very wise man" I referred to in my previous post!  ;D

I used type f in my KTM 200 with no issues.  I am sure that transmission took way more abuse than a rd trans does.

Great Stuff and worth the money
