Greetings ShopForum,
Regarding the topic, you are more likely to ignite a holy war than hear objective advice. My personal experience with the BG product line (44k and fuel injection cleaner) in several vehicles during the past four years has been very positive. I also intend to give the Auto-Rx (
http://www.auto-rx.com/) engine cleaner a go in the near future.
These have been stated in different ways by other respondants.. but here are some good rules to live by:
- Choose stations that are frequently refueled (i.e. close to a highway exit).
- Always choose a station associated with a well-known brand (Shell, Esso, Chevron, Amoco/BP, etc.). Base fuel is often sourced from a single refinery for a region, but detergent quality really does make a difference.
- Rotate between at least two brands every other month or quarter.
- Do replace your fuel filter(s) on schedule and routinely check your fuel lines for leaks.
- Avoid stations at the bottom of a hill or in a valley -- these tend to have greater risk of contamination during rainfall.
- Avoid stations with older pump equipment, and thus older storage tanks more susceptible to contamination. Just ask me how I learned this valuable lesson :-(
- Avoid fueling your car while the tanker is fueling the storage tanks, old wives tale or not.
Just my humble opinions,
-DM
