I asume I'm the "OP", since I'm 61 I've seen it around for sometime now. I'm just new to post this at a site like this one, so I did it to see what the group would point to as the reason it's gotten "thinner". Thanks Bruce
Troll? I have been using 5-30 or 5-20W in my Subie while towing, and not many track days in the Stang. maybe more in the future in the Miata, I can always go up to a 5/30W when that happens. Thanks for the replys.
