Which octane for a '95 525?
I'm about to pick up one for my mom. 100K miles on it and she literally only drive about 5 miles a day to and from work. I'm hoping that this car will inspire her to get out more, but none the less it will be bone stock. What will be the best for this situation?
Thank you.
the m50 and m50tu in the 525i are only supposed to use 91 or higher gas....the 1995 525i has a knock sensor so if a lower grade of gas is used it won't kill itself, just produce less power, but you should try to stick to the 91.
