Hi all...I recently found this forum, and it's great! I've learned more about oil in the past week than I've known for my 36 years!
With that, I've decided I'm switching over my '93 Caprice 350 to M1 (10/30 summer, 5/30 winter). I've been running Phillips 66 Trop Artic (only 'cause I'm a stockholder!) every 3K, but decided through this board and my brothers to go M1 and extend my drain intervals to 5K. It just turned over 200K last week, so I'm hoping this'll add to its life.
But, my weekend toy is a '65 Corvair, 110. I have been running, again, Phillips 15W40 HD-II in the cooler months and Phillips 20W50 Racing in the summer. 15W doesn't do the best in the summer with its tired engine as well as the heat the oil takes in a Corvair, so that's why I run 20W50 in the summer months. I've also decided to switch to synthetic for the Corvair too, but I'm still wanting to put a 20W50 synthetic in it for the summer. What brands (I wish M1 had a 20w50!) are OK and what should I avoid?? I usually put about 3K miles on the car per year (Weekend Warrior!). My local Advance has Red Line and Auto Zone has Valvoline Syntech, but the pickin's are slim for other 20w50 syns. Thanks in advance!
