I was just wondering what is the best way to collect a sample. I have a stock 5.3L in an 02 Silverado. Is it possible to run a tube down the dipstick and pull oil out that way. Of course I understand that the engine has to be fully warmed up and at operating temp. I figure I would collect it right after my trip home form work which is a 20 mile highway run. Should be good and hot by then. Don't plan on draining the oil but want to collect a sample to see how things are holding up. I currently have 25k on it now with 3k on the oil. This will be my first sample. I'm sorry for waiting so long but money is tight with a new house and all. I really want to see how the engine is holding up. I figure I can run a tube down the dipstick and pull out some oil with my brake bleeder, just making sure that I use a clean tube and catch can. Does this sound right?
Thanks
