my sister has gc in her car. its been in sence april.
today is her birthday so one of her friends took her car in to get the tires balanced and the oil changed as a present. thats $20 in gc and a prefectly good pure 1 oil filter down the drain. you want to really cringe at what they put in her car? accel brand "api sf" 10w40 oil and some unknown filter.
they also changed her air filter. her old one was only 2500 miles old, and it was a nice wix filter. the new one is an unknown brand.
this is one of the downsides to using an expensive oil. whatever can go wrong, will go wrong.
how about the time a year ago i had saab turbo oil in my motorbike. 2 days later i lost oil pressure one day and had to dump the turbo oil so i could open the engine up and replace a little o ring that had blown on the oil pump.
it seems like synthetic is almost not worth it because "things" happen in which you have to lose the oil early, weither its the fault of a little o ring, or a stupid friend who thinks she is doing good.
how many of you have been forced to dump a synthetic oil early because of some reason for which you could not control?
