I am simply curious what everyone is doing re Engine Oil.
Every 3K, 5k, 7K, 15K.
FYI, I came across this site on a BMW. BMW Oil Change Interval recommendation of 15K per onwers' manual!!!
This confirms my long-time suspicion that car mfg's increase the "usual" engine oil change interval of 5-7K to 15K to make the car looks better (car salesman often brag about "low cost" of maintenance "oh you don't need a tune-up until 100K kind of thing"...)
Whatever, I am doing my oil change in all my cars at 5-7K.
Not starting a debate but simply curious what everyone does re "Interval between oil changes".
