    How do you guys figure out how many hours is on your equipment?

    Do you guys have hour meters on everything? :confused:

    I use Amsoil in everything. Figure it's a cheap alternative to using cheap oil. I use all synthetic even in my diesels, runs cooler, better performance, longer life... the list goes on and on. I recommend Amsoil but any good name brand synthetic is good. Just look at the price first, that will tell you which one to buy...

    Used to used Mobil 1 full synthetic but that got expensive, now we use Supertech (Walmart) synthetic for all gas engines and Rotello synthetic for diesel.

    I hope you do realize that outboard oil is intended for water cooled engines only, right? I would guess that these mechanics are dealer mechanics trying to sell more new machines.

    I run the Kohler straight 30, and Stihl synthetic in the handhelds. I change every 50 since I don't rack up hours as fast due to part time use.

    Gas engines straight 30 Valvoline, every 100hrs oil and filter. Diesel every 250 hrs for oil and filter. I use the recomended JD oil for the diesel.

    If you need a hour meter get a Tiny Tach.

    Do you have any proof that the synthetic makes you engine run longer? I hear everyone saying this but I have never found someone who has run two of the same engines side by side on synthetic and one conventional.

    This is the problem I'm running into. I was using Quaker State SAE 30 and by 50hrs it was black. I could never make it to the 100hr interval. So I decided since I like the Opti-2 so much, I'd try the Opti-4. It's not synthetic like most people think. Even after using that (which is way expensive) I couldn't make it past the 50hr mark. This is why I started this thread so I could find out what is working for you guys out there. Am I going to get 100hrs out of a synthetic? Or should I just go back to my Quaker State and change it often. Which is better? Or is there another option?
