Fuel and repair costs are rising…
Why not make your (overpriced) fuel work for you? If you appreciate your internal combustion engine, and want to help avoid costly repairs or maintenance to your fuel injector system, you can! To be honest the quality of fuel is often questionable (I’m looking right at you, ethanol). Modern fuel injection systems are squeezed for every iota of fuel economy and performance. It makes sense to be a little proactive with the preventative maintenance, it’s just good sense. Adding Jectron to your fuel is a smart, and economical measure that you can take, to keep your injection system running as designed. It won’t damage your emissions components, it won’t harm your fuel systems more delicate parts (O-rings, plastic tubing, filters, etc.). There are plenty of great options out there, such as Chevron’s Techron, and a handful of other reputable products. I used to be a very strong advocate of Techron (it’s still my backup choice). However, after witnessing Jectron solve a battery of problems on a variety of vehicles, I’m a convert.
