Re: New available motor oil

I'm still a little mystified, too. Is Valvoline "Conventional" which is available here, a non-synthetic oil? As posted earlier, it is specced as API SN/SM. I don't know what that means.

As far as what's available in other states, that seems to be all over the map. Heh heh. Lame. If I find out any more, I'll post, but someone may already know how to find out what's available where and what specs to look for.

I've had good luck with Valvoline in the past. I don't see anything wrong with using a multi-weight, but I use straight 30, and still add some MM oil.

The thing about having that thinner oil on starting is to get lubrication moving through the engine quicker. The thing about using MM is that it adds viscosity strength (at least claims to), and will leave a thin coat of oil on everything, also making startups a little easier on the moving parts.

As we've heard over and over again, much of the wear on an engine occurs at startup.

Something else I have against synthetic (as opposed to the synthetic "blends" (of which we have a lot around here) and the old conventional oils, is that straight synthetic gives very little rust protection when an engine is sitting for long periods. It's so slippery it literally slides off the parts and, depending on conditions, the insides can start to rust. NOT good.

I'm not concerned too much about the oil change I'm doing now... it's really going to just be a "flush" and changed fairly quickly. At some point, maybe next year, I think I'll try that Lubriplate stuff at the link offered earlier. Even with shipping, it'll cost about the same as the Valvoline I just bought.
