I usually put my summer car away for winter this time of the year. I was wondering if there are any issues with Redline Oil left in an engine year long, mainly regarding seals ?. I once read that Group 4 & 5 base oils can be hard on seals , but manufacturers use additives to make them more compatible with seals.
I often dump the summer use oil and put in fresh oil for winter storage right about now. Last spring I changed to Redline oil for extra protection on a trip to the Dragon (Deal's Gap). I think it worked well as the wear levels on my UOA were about as good as a typical daily driven UOA , despite lots of high rpm and high-G forces driving on the Dragon trip. In spring 2016 I may be going back to the Dragon, so I've been considering running Redline oil in the engine and leaving it over winter. Any opinions about Group 5 oils and seals during long term use ?. Thanks for reading and any opinions.
