So I go back 2 weeks later which was tester day and got 5w30 full syn oil changed drive home and all day good well I got up this morning and as I pull up to my job the check engine light came on could it be from my oil change it says emissions workshop on my dash but the car runs too good for the year it has 116xxx on It what could it be should I be worried at all
Now, my favorite car has always been BMW 840 / 850 – – I'm sure there's a difference but they look the same to me…
Say I buy this car and I want to change the engine, I hear it has a big engine (V12, whatever that is) and that it's eating a lot of fuel…which in turn, costs a lot of money…
Now, could it be possible to replace the engine with one that has a smaller gas consumption?
I'm sure there's a lot of paperwork to do but could it be done?
I apologize for my English, it's not my first language.
Thank you for all answers.
Also, please don't make fun, I really like this car for the way it looks, I dont want to race with it )
