I pulled the intake manifold off an old Chrysler and you couldn’t see the lifters as they were covered in wax. Old paraffin based Pennzoil.Ya weren't exposed to many Wingers, were ya?
And in 75 the Wing was only .2 second behind the Z1. I ran the crap out of my 75. When I sold it the thing had about 55k on it. Couldn't get carb parts for em back then.
And now 10-30 is crap.
As to the QS recall it wasn't due to the grade of the oil. The oil wasn't made properly and only select batches from two refineries due to a problem with the additive package received.
Other brands of 10-40 had no problems.
QS was a wax based oil, hence the sludging. My son worked at a oil change place. They used Pennzoil. Same problem with the sludge. He said you could tell a regular customer by looking at the bottom of the filler cap. They sold a lot of oil flush services.
