Hi all I have a 2018 1.5 auto transmission oil change with 55k and I know the Dealer says the AT oil is lifelong and doesn't need changing but I want the car to last a few more years without issues. My local Indi has quoted for an oil change but the oil is not available just yet and might take 3 weeks to get some. I have BMW extended warranty which ive never used as its been ok but the car makes a different noise for the first 5 mins of driving in the morning so im thinking of not renewing the warranty and changing the oil as it will be a lot cheaper. is this a good idea or should I not change the oil and keep the warranty. I can't make my mind up
thanks
