I just had an oil change done at a chain franchise to the tune of $75. My question is, how can I be sure I ended up with the full synthetic oil I paid for? Is there a test other than lab analysis or is the process regulated to insure honesty?
I don’t think Ray ever answers questions here . Why not just return to the place and ask them to show you the drum they pumped the oil from . Frankly I myself would not even worry about it and the next time go some place I could trust.
