Honestly after I purchased the car, I looked a bit deeper into the hostory of the car. And the previos ownerlooks to have missed 2 service intervals.
Had I known that I probably would have not purchased the car. My heart 1 out
So I do this as preventative maintence, BG44K avery 7,000. and maybe 2 bottles of SL1 in between. Of course 93 octane.
The car is in good hands now instead of some abusive pricK, that is not able/want to service the car, with 70K on the clock, I cant afford a new motor at the current time, so I am careful period.
