Re: Oil Consumption 2000 JGC V-8
Technically STP was a Granatelli product... the guys that scared the bejasus out of the Indy 500 folks until a bearing gave loose.

Re: Oil Consumption 2000 JGC V-8
From the STP website:
"In October 1954, three businessmen with a mere $3,000 in start-up capital introduced the first STP® product in St. Joseph, Mo. Scientifically Treated Petroleum, better know as STP, began with one product � STP® Oil Treatment � that helped automobile motor oil resist thinning at high temperatures and pressures. The group, composed of Charles Dwight (Doc) Liggett, Jim Hill and Robert DeHart, began packaging STP® in a backyard garage. They packaged it at night and sold it from the trunks of their cars during their business and pleasure trips. The company�s initial growth and profitability � attributed to strong word-of-mouth and the brand�s link to auto racing � enabled STP to introduce its first Gas Treatment in 1960. In 1961, STP was purchased by the Studebaker Packard Corporation. Andy Granatelli was appointed CEO in 1963 and began to increase the brand�s marketing efforts through auto and boat racing. Eventually, STP sponsored its own Indy Car racing team, featuring Mario Andretti, the winner of the 1969 Indianapolis 500." However if I remember right the three businessmen actually acquired the formula from the German Army and STP started life as a product that helped the German war effort in WWII.

Re: Oil Consumption 2000 JGC V-8
Aside from all the other comments, if it is suddenly using more oil than
normal, then ignoring it will just accelerate engine deterioration over time. The oil contamination creates excess carbon deposits that increase wear throughout the engine -- especially the piston rings. It could be that the valve seals are going bad. I would think that valve seals may be fairly easy on that engine -- once the cam covers are removed. Just getting them off may be a challenge in itself since they're sizeable magnesium castings and there are things in the way. One possibility would be to determine if there's any blue smoke in certain situations. It may be faint so you may have to ride in a second vehicle trailing your Jeep on a sunny day and watch carefully for puffs of blue smoke. For example, if there's a puff of blue smoke upon initial acceleration after idling for a minute, I think that would suggest a valve seal issue, since the higher manifold vacuum draws more oil down the valve guides into the cylinder during deceleration and idling. It's not burned much during that idling/deceleration phase, but then when power is applied the oil is suddenly burned, creating the puff of blue smoke. If you see any blue smoke but it's fairly constant, rather than a puff here and there, that would probably suggest worn rings. This is certainly a possibility since, on the 4.7L, the distance from the top ring groove to the top of the piston is only 1/8 of an inch. That 'dead space' between the piston and cylinder wall above the top ring tends to trap unburned fuel, so reducing that space improves emissions. But then the rings are more susceptible to wear and heat since they're pushed closer to the combustion chamber. The wrist pins also tend to be higher up on the piston nowadays to allow use of longer connecting rods for improved torque, and this means thinner rings which are more crowded together at the top of the piston. The oil consumption may not be great enough to create noiceable blue smoke, though. And, of course, there are other possibilities. A head gasket problem could allow oil to seep into a coolant passage, so make sure no oil is getting into the coolant...
