I had penzoil put in by jiffy lube the last time i did an oil change on the focus. This was 2500 miles ago. Ofcourse my mechanic while doing the 60K service put in valvoline.
For that 2500 miles on penzoil (2nd time i ever put that crap in) the car ran like crap & sh*t. I mean i didnt see more than 270 miles to a full tank of gas(reserve). Today on my drive down to LA from Sacramento, I hit reserve at 350miles. This was with teh aircond going on and off periodically as needed.
Some how penzoil seems to make my engine run really rough when started and then after teh engine is warm it still runs like crap. With valvoline it seems to run so much better. Power is so much more available and i can seem to actually feel the engine run smoother.
THe last time i ran Penzoil was in June of last year, and i changed it out within 1500 miles. This time i got to 2500. I usually do 5000 mile oil changes.. god had i kept going for 5000 mile oil changes it might have ended up doing more harm to my engine.
I also noticed the car runs cooler with things other than penzoil. At warmed up engine (proper operational temp) the water/coolant temp sits a tad bit on the right of center. With every other oil I have used (mobil 1, valvoline, motorcraft etc) it sits on the left of center. It seems penzoil makes the car run a tad bit hotter, dont know why. Today it came down all the way with the temp a tad bit to the left of center.
I think the only thing penzoil is good for is when you rebuild an engine and use it as break in oil.
oh well that's my rant for this evening..
