I LIKE CHEAP STUFF.....
Before we went to the beach last week, my car was already around 500 miles overdue for an oil change. I have always just ran Castrol GTX conventional oil in whatever I drive with delco or whatever filters. I always get it changed at local jiffy lube because it's so much quicker than me fawking with it. So anyways, I did not have time to get it changed before the trip so was gonna stop by last Monday morning on our way to the beach and get it changed....well they were closed. So I went down to the one in the neighboring city which was a Mobil1 branded jiffy lube place. He asked me which oil I wanted and proceeded to explain they usually put Mobil 1 synthetic blend in as their basic oil change and that you can drive 5,000 miles before next oil change will be needed. I assume a synthetic blend is same as a semi-synthetic oil. He also went on to say if I chose conventional oil, it's the same price as synthetic blend, but I can only drive 3,000 miles on conventional. Of course full synthetic was like a $15 upcharge but you can drive 8,000 miles on that.
Now why I've always stuck with conventional oil is mainly so that I don't just run it a long time like 5,000 or 8,000 miles and it be getting low if it burns a little oil per oil change, because I'd probably never make myself keep a check on the oil level throughout 5-8k miles of higher dollar oil and filter. I've heard different opinions, most don't think semi-synthetic is a good choice it seems. Some swear by full synthetic 100%, some only swearing by it because it costs the most and "you get what you pay for", some say fully synthetic is not good to run in a vehicle after it's only had conventional oil in it most it's whole life. Had a buddy have a Harley Davidson deuce that he ran synthetic oil in, noticed tiny leak on garage floor while it was sitting, someone told him to switch to conventional oil, he did and he had no more leak. The reasoning I've heard behind that is that the molecules of conventional oil are all about the same size, whereas the molecules of full synthetic oils are different sized, some small some big, allowing full synthetic oil to seep through around seals and such easier than conventional. No idea if any of that is legit. Some people say most all oil is the same long as it has the JASO or whatever it is rating on it.
So what are you guys' thoughts on oils? What do you prefer and why? How long do you run oil in between changes?
