What are your experience of FP with different brands of gas?

[sifan]

Last night I refueled at a Chevron gas station in MD and saw the tanker was pumping fuel. I walked over and talked to the driver beacasue I did not see the name Chevron on the tanker. He was very friendly in answering my questions. His knowledge in gas delivery business basically confirmed what I had learned from this forum. Anyway, he said the additives are harmful to the engine despite they help clean burning. I did not ask him to elaborate his comment, but I assumed the harm came in the from of carbon deposits. He also suggested me to buy the chpeast gas in my area because he basically delivered gas to all the gas stations around here.

Ever since using FP/LC I have always sticked to Chevron. After the conversation with the tanker driver I wonder if I should follow his advise to try the cheap gas. For those FP users out there, do you get the same performance and gas mileage with FP on different brands of gas?

sifan, outside of my association with LC/FP I have also discussed with many tanker drivers and they advise to just buy the cheapest gas as it all comes from the same place. They have also mentioned the amount of additives added in various brands at the station are not enough to help much. Also mentioned by many drivers; the cheaper the gas --> the busier the station --> the fresher the gas is --> the cleaner the tanks are.

sifan, be careful where you buy gas. I had a new Honda in 1994 and my wife called and said it would not start one morning. The Honda was only two months old. I asked her where she bought gas on the last fill-up. She said the Crown station by our house. I got the Honda started and turned out there was water in the tank. Next month the Crown station changed tanks. If you don't have problems with what you buy now, don't switch. A few cents is not worth changing.

I believe all the gas stations in MD should have new underground storage tanks now. I do not know if this is true in VA. The Costco gas station in Sterlin, VA, always has long lines of customers everytime I pass by. I refueled at that station once (prior using FP) and did not get as good gas mileage as from Mobil. My past experience from those no brand name gas tells me to stay away from them. Maybe my car's oxygen sensors are accustomed to a particular brand of gas.

Well, if it isn't broken, why fix it, right? I guess I will stick to Chevron then. But, I still love to hear your FP experience on various brands of gas.

My car seems less sensitive to various brands of gasoline now that I've been using FP. It even performs well on the gasoline I siphon out of old parts cars at work! MPG doesn't really change much anymore...It's been pretty consistent regardless of the brand of fuel.

I only get gas from 4-5 gas stations in my area that I trust (meaning I have tried their gas a couple of times and the car runs fine). Most of the time I stick with Mobil. With the FP added, I don't see a noticeable difference in gas mileage or how my car runs.

"... he said the additives are harmful to the engine...." I'm not going to believe this until I see some competent technical documentation. The additives are essential in gasoline to make a functional product.

Here in the Northwest, I've noticed a mileage loss with BP's ARCO gasoline, but no problem with any other brand including the gasoline sold at Safeway & QFC supermarkets. We've got five local refineries...Motiva (Shell), Tesoro, BP (ARCO), ConocoPhillips (76, Conoco, & Circle K), and U.S. Oil. And one pipeline from these refineries to distribution points around the region.

I basically have three options for gas during my normal commute; Mobil, Sunoco, and Bee Jay's wholesale club. Mobil always works great, great mileage and no pinging. Sunoco seems to drop my mileage by 5-10%. Bee Jay's gas makes my rough idle come back and it pings like crazy, that stuff is CRAP!

Mobil 87 with FP is my fuel combo of choice in my '01 XJ. I see such a difference between these different sources that I have a really hard time believing it's the same gas with different detergents.

If you were to get the cheapest gas and add FP would this make up any "missing" additives over using Shell, Chevron, etc? I've wondered this. If FP will clean and give you better mileage why not use the cheap gas???

 

[phordguy]

In my area I get better gas mileage and performance using the cheapo gas with FP, 1oz per 5 gal, than using the name brand stuff without FP. The real kicker here for me is that the name brand gas is at least a dime or more a gallon and this costs more than the fuel power, so I'm saving a little on initial cost (since I always used name brand gas before thinking it was keeping the system clean) and getting more value for my money due to higher mpg thus extra savings.

We don't have any "economy" gas stations around here. Even the gas sold at places like Fleet Farm, Woodman's and Piggly Wiggly are the same price as the "good" stuff from Shell, BP, Mobil, Citgo, etc. Our Sam's Club doesn't have gas like a lot of them do, and we don't have a Costco up here. Used that gas a lot when I was out in Phoenix though. It ran ok, no gripes...It was as good as the rest of the reformulated, oxygenated swill out there, so might as well save money on it.

I'm asking because I live in an area where just outside of town are several large gas tanks and I believe all of our area's gas comes from these 2 or 3 tank "farms". If I were to get the Kroger gas and add FP would this be as good or better than Chevron/Shell/etc w/o FP? The Kroger is selling gas cheap here and I figure they get it from the same tanks outside of town just use a cheap additive pack.
