Frank, Following your link to Mathy provided lots of info on that product. At first I thought the engine SAE 0-50 numbers seemed too high, but their explanation of using 10% Mathy/L of oil explains the high SAE number. I'm not up on the ERUO to US dollar conversion,but I would think at least for you it's cost effective. What are your personal opinions and how long have you used Mathy?
Oops.Just realized this topic took a big turn from the original post.Sorry about that.
