Sorry for the non LBC content but I figure this list will have the answer to
my question.
I've got a 2004 VW Passat 1.8T that "requires per VW" premium gas. Last year
when Katrina pushed gas over $3.00 a gallon I tried running the car on
regular 87 octane and saw no change in performance. I know that today's cars
have anti-knock sensors that (I think) advances/retards timing to prevent
knocking at the expense of performance. Since then I've gone between premium
and regular and can see no difference. We just got back from a week of baby
sitting the grandkids and I averaged 32 mpg at 65 mph for the 700 mile round
trip, all run on regular 87 octane.
My question is: is there any long term impact from using regular gas other
then more $$$ in my pocket?
Thanks
