And also is it bad if reg DINO Oil was put into an X3 2.5 instead of Synthetic? The X3 was always changed with synthetic but this time...well DINO oil was put in.

Best oil in the WORLD..I use it in everything I own from 60psi turbo diesel truck, to stock civic, to lawn mowers, to jeeps, to cadys...

I use the Synth 5w40 until it hits high temps 90+ outside then I use 15w40
