Oil Change Problem Requirement question?
Hi - I am trying to help out a family member by getting some quality info. I was really impressed with some of the random threads that popped up from this site in my random google searches.
Basically my relative got tired of paying $90 for an oil/service change experience at the dealer, so they tried someone else.
I believe they did two; possibly three oil changes with them in a period of 12 months and paid $30 each time. Some months ago more recently, after going to somewhere else, they were advised by that service manager that the IS-250 requires 6.7 quarts of oil & a special filter change as well each time and the total came to $42.50.
The $30 deal they were getting from the first place was a bundle type deal that only covered up to 5 quarts. So either two things happened. They made a mistake and did not bill properly or they did not look it up in their system and did not give the proper amount of required oil and special filter. Worst case scenario, and assume they screwed up, what kind of damage could the vehicle have suffered before this revelation came about??
Also, unrelated question, but when the alert goes off in the IS-250 that says required oil maintenance needed. Is that just based on some primitive type programmed mileage calculator in the system or is their actually some kind of intuitive function happening within the vehicles logic board that reads the weight/quality of the oil?
Thanks in advance.....................
