I have been using Super Tech oil for years to some degree.I use it in my mower and have used it in a GM car for many OCI's and miles.I have also used the Super Tech oil filters but since the switch to the E-Core version,I am not to thrilled with them and dont know if I will use them again.
The GM car has around 225,000 miles on it and quite a few of those miles were with Super Tech oil and it uses little if any oil and runs good.When you look thgrough the oil fill,it looks good,no sludge or anything.
I am planning on using Super Tech oil for my next oil change in a Ram truck.I will probably go with a filter from Auto Value Auto Parts,they are Affinia which is really a WIX made filter.
Since the switch to SN,I think that just about any oil will work and you wont have any problems,the base oils are really good these days and Super Tech is made by Warren,XOM and possibly Shell.While these oils may not be the same as the name brands that are made by these companies,they are far from junk.
