Just thought I would mention another great product that I use that seems to be working very well. Sly’s snake oil is a must if you are running any diesel engines on the low sulphur fuels that now are being sold at all gas stations.
I use it in my Yanmar tractor and have had great results. The tractor starts way easier than it did before and the valve train noise has quieted down substantially.
Not to mention it comes in a very cool can that I plan to re-use and make into a super cool cigar box guitar / Canjo.
