Forgot to attach the picture
do you have a pic of the bottle?I only gas up as Chevron and use Techron additive about every 750-1000 miles. I also drive my car hard.
Not handy, I'm out of town, but I buy the 6 pack of it at Costco.do you have a pic of the bottle?
My 740 had plenty of umph. More than enough I always thought. Still would have liked to test a LCI 750 though But overall, the 750's seem to have alot more problems and when do you REALLY get to use that extra HP?? From green light to green light? The inline 6 is BMW's bread and butter. Even the 550's are having the same issues. They need to seriously redo the twin turbo V8 to figure out how to get rid of the carbon build up. Not sure why "most" of the 740's dont have this issue since the design flaw seems to be the direct injection, which is what the 740's have as well, hence they should be having the same issues as consistently, but they dont.I swear by Techron in my Galant and 740LI. I also have a long hour commute and on days I drive the 740 there are some long stretches that I open it up 110+ I'm pretty sure that blows out the carbon as I have had no engine or rough idle issues.
I also think BMW hit a home run with that 6 cylinder they put in the 740 and other models, as I rarely hear any issues engine related. Not sure that extra one second 0-60 is worth all the issues.
I was going to mention the battery to you! If your car is running smooth except on 'colder' days, check the voltage. BMW computers are very sensitive to battery and misfires and random faults are a few of the symptoms especially when the battery gets to 4+ years. Online, the battery can be had for $350 OE.I think I know the source of all my faults! mon when I went to start the car(it was very cold) the battery warned me of a low charge. 5 yr old battery, when I had the drivetrain fault (alone with 34 other faults) it was very cold. my guess is that when the battery was going it could not maintain sufficient voltage for all the computers, low voltage could easily cause a computer to fault.
battery replacement was $600!! yikes
I cant believe but it helped.Thx for the advice!!! Short video how its runs right now
