Congratulations on your new lawn toy. The Fram 3614 definitely fits the Briggs V-Twins, and I think it also fits the Kohler's. I used Lucas Red 'N Tacky for the first five years on my JD, but switched to Mystic JT-6 High Temp last year due to oil separation with the Lucas. I can't say that it caused any real problem, but I didn't like the way the grease gun was leaking. As for motor oil, I favor M1 10w-30 High Mileage for its 3.5 HTHS rating.
