I had an OilGuard #20 on my 4-banger (I love over-kill when it comes to oil). Had it removed before trading it in. I now have a GM 3800 that is off-warranty. The mechanic that did it to the 4-banger will call me with short notice and install it. Should I use plain dino the first while? Or synthetic? I have an ample stock of Redline as well as GC and A-RX. Current fill is GC with 12 oz A-RX and Schaeffer's Moly, in for 4 months or so.
It may also be that due to bangings / rude dents on my oil pan, a certain place may drain my oil perhaps as little as 2 weeks prior to the installation of the by-pass. If so, does that mean that any old oil will be fine? Or should I drain the oil ASAP and run a second dose of A-RX for max cleaning before going to the bypass filter?
Advice is warmly appreciated. THANKS!
