Dave. Only one dealer for Stanadyne in the province it looks. Ive heard good things. Most guys here run KleenFlo... because its cheap and available everywhere. Howes is too.
I remember reading a comparison that compared the big brands of additives, wish I could find it again.
You might be thinking of that Wear Scar test. Interesting data, from what looked like an independently done test. Sorry, don't have a copy handy.
'Dyne Performance Formula didn't place all that high, as that is a lubrication test. So, I run their Lube too. Also liked the no alcohol aspect. In the additive that is.... I'm fine with alcohol for other applications ! :drink:
Dyne additives are pretty pricey here too (Central ON). I pick mine up at D&W Diesel, upstate NY. Haven't asked, they might ship to Canada ? Looks like closest dealer to you would be Bangor ME. USA pricing is no more than half what I've seen here.
If you want to try a small bottle locally, I've seen 'Dyne at International dealers, and also one NH dealer in Canada.
I always hear good things about Howes, and I've used Kleen Flo in gas applications. I liked how 'Dyne approached the water issue.
Rgds, D.
