#FuelSystem

Hi Sajeev, it’s me again. I am nearing my wit’s end.

My Impala has been out of commission for several months now and as I’ve been telling my friends, the Land Ark and I are not currently speaking to each other. What got us to this stage of our relationship is my seemingly brilliant idea of upgrading my fuel system. I had been concerned about the E10 used in gas stations currently and fearful that we’d soon be provided E15 that would likely start accelerating the degradation of my fuel lines and carburetor bits. I’d purchased a replacement gas tank and sender a few years ago and I found a guy who I thought I could trust to replace my tank and all my fuel lines. I put in everything that could potentially survive E85. I was willing to pay for quality and I did. Everything was replaced but the carb.

Dear Sajeev,

After reading TTAC for many, many years I succumbed and finally got me some panther love. It blows my mind that Ford can make such a well-balanced, corner-carving sedan and then never sell it to civilians. I traded my 2006 Mazda 3 for a 2006 Police Interceptor Crown Vic (170,000 miles). The aftermarket exhaust makes it growl and it parts the sea of entitled BMW drivers hogging the fast lane like a dream. Unfortunately, due to living in glorious urban hellscape that is Oakland, I have to pass smog regularly.

Sajeev, here is a possible line of discussion: ethanol fuel. It’s hard to find straight gasoline now and impossible in the more populous counties of Texas. E15 is around the corner. My old D21 is still running strong at over 200K (previously discussed here and here —SM) but I fear that adding E15 might be the kiss of death for its early ’90s system.

Additives, alternatives and a point of discussion?

Hi Sajeev!

I’m a long time lurker, first time asker. I was curious about the effects of E85/E90 ethanol laced gasoline. I have read a bunch about how older cars are susceptible to corrosion damage to various parts of the fuel line.

Sajeev,

Longtime reader, first time writer. I love reading your stuff, well worthwhile.

My query is about fuel additives, after-market specifically. I have used the Lucas Oil products and found them to produce a mile or two better MPG in my 94 D21 four banger. (Note: that’s a Nissan Hardbody – SM)

What is your take on additives? Have you found any others to be of significant value to the user/user’s vehicle?
