Thanks for the tip, but I just can't go there, even in my Briggs&Stratton.

I changed oil for a living for a couple of years.....there are a few of the bigger names I wouldn't put in any engine I own.  Quaker State is one of them.

i agree with buda..i would'nt put quaker state in anything i own..my mother inlaw had a car a few years ago that needed a valve cover gasket..she ran nothing but quaker state motor oil..when i removed the valve cover there was so much parafin wax in the cover.
 the wax was so thick that the rocker arms were actually surrounded by the stuff. it was caked in there 4 inches thick. after seeing that..i would'nt have wanted the job of tearing the rest of the engine apart..i could just imagine how thick it was in the oil pan.
 quaker state always was pround of boasting that using their oil eliminated most engine oil leaks..i can understand why..the wax builds up so thick. it's impossible for the oil to find an excape route.

got me wondering, found this..

Myth #1
Paraffinic oils cause engine sludge. Oils from paraffin-based crude are loaded with wax and create engine sludge. Paraffin base stocks cause sludge. "x" Brand of motor oil causes sludge, varnish and/or engine deposits. "Paraffinic" motor oils cause wax-like deposits on the underside of the oil fill cap.

Fact
There are two basic types of crude oil, naphthenic and paraffinic. Most conventional engine lubricating oils today are made from paraffinic crude oil. Paraffinic crude oil is recognized for its ability to resist thinning and thickening with temperature, as well as its lubricating properties and resistance to oxidation (sludge forming tendencies). In the refining process, the paraffinic crude oil is broken down into many different products. One of the products is wax, and others are gasoline, kerosene, lubricating oils, asphalt, etc. Virtually every oil marketer uses paraffinic base stocks in blending its engine oil products. Many people believe the term paraffinic to be synonymous with wax. Some have the misconception that paraffinic oils will coat the engine with a wax film that can result in engine deposits. This is not true. The confusion exists because paraffinic molecules can form wax crystals at low temperatures. In lubricating oils, this wax is removed in a refining process called dewaxing. Wax is a premium product obtained from crude oil, and in order to ensure that we produce the highest quality base stocks available, Quaker State® removes the maximum amount of wax possible during the refining process. The end result is a motor oil product formulated with premium lubricating base oil.


a little knowledge is a dangerous thing

So, if this is a rebate on Quaker State Synthetic, which would not use a naphthenic or paraffinicoil stock, what's the issue? 

I've used the synthetic in our cars with no issue.  The previous mini-van we had also had a leaking head gasket that I replaced and the engine and cover underneath were pristine at 150K miles.   

Plan to use this coupon to get some more oil for that vehicle. However, the Valk gets Rotella or Delo.

beats me, but I thought the whole wax thing was funny.
