If you change the oil after every race as should be done on a race motor filter quality is not as important as if you were leaving the oil in for a season. I usethe WALMART 4967 on every mower I have with an oil filter. Cheap and worksjust fine considering I change oil as said above.
Will check into the Walmart 4967, been using the fram 4967 with NO issues.
Agreed, if you change the oil frequently, probably don't need a filter. Definitly change oil when it's warmed up.
I change the filter every other time I change oil.
Speaking of Walmart, I could not resist trying thier Fully Synthetic "Tech" brand oil. It's less than $4 a qt.
That almost seems scary(too cheap?)
Have not tried it in the twin yet, but, it is in everything else including the home domestic small engines.
No problems so far. Very happy with the price.
How do they sell it so cheap? I says "Fully Synthetic", and they have "Synthetic Blends" too.
What could it be missing?
Can there be that much of a mark up on this snyth oil?......I have been using Mobil-One Synth in all my cars and mowers....I swear by the stuff. I have some Amsoil too that I use sparingly-$$$$. That is really good stuff.
