Just a couple of things that I have found here recently. I had been using stihl premium synthetic oil for awhile now. I would buy a case of it and then a case of Pro Mix which is also ISO JSCO approved. While it is not the be all end all of expenses I found it of course does add up especially over the course of a year. This year what I have found. After reading years of Amsoil threads on here and listening to there reps jump into every thread.........I found it while buying oil and filters for the mowers at a local NAPA I found the quart size bottles. They are just roughly over $9.25 there. I asked the guy if that was the normal price everday. He confirmed it was. Now I am not a big believer in attempting to run it at 100:1 or even 80:1 but even at 50:1 which I run it at it is still works out to be less than Stihl for sure and it is cheaper than the Pro Mix that is a approved oil too. I suggest checking it out. The only down fall that I see is that it is not pre-measured and convient like the little plastic bottles, however if you carry a little measuring device in a ziploc baggie that you can attach to the bottle it is just as easy. A much better price for a ISO approved oil. Next I am not a big believer in snake oils but am growing concerned about the potential of ethenol and its effects on the equipment long term. I did a lot of research on here and everyone who uses said products seems to like Seafoam. Well I used one bottle recently and thought it might be ok. Went to Wal-Mart the other day and was just browsing as it was a new store here in town. Found this product which appears to be in the same exact bottle and claims to do the same thing. Again it could be snake oil but for those of you that do use Seafoam...maybe this would be better? It is much much cheaper as you can see in the picture. Have any of you used it? Any other cost saving measures that you guys would like to share that you have found recently or over your time as a LCO?
