Default How can I increase gas mileage?!?!

Hello all. I have a 1994/1995 Chevy S-10 Blazer with a Vortec 4.3L CPI engine. Right now I'm getting some pretty bad gas mileage. I just wanted to know what I could do to increase my gas mileage. Because it's technically a 94 I won't need emissions, so if it isn't "street legal" it won't matter. Please tell me what I can do, where I can get the stuff, and how much it generally costs. I'm moving to Illinois to go to college and it would be nice to get some better gas mileage for when I drive home on the weekends.

THANK YOU.

Basically alls you can do is have your truck as light as possible, Accelerate slow, basic maintenance like changing oil, oil filter, plugs, and plug wires. Make sure your tires are inflated properly. Drive the speed limit. 65 on the interstate, and get you a K&N air filter from autozone for about 45 bucks. Clean out your throttle body and butterfly valve. The throttle body cleaner is found at autozone for 5 bucks. Run some Seafoam through your fuel from time to time. Make sure your fuel filter is good to go. Thats about all you can do without buying a new egine and re gearing or so or finding some lighter tires lol. The biggest thing you can do is drive the speed limit around town and accelerate slow and dont forget about 65mph on the highway you will love how much it saves you. Hope this all helps. Good Luck

Use OEM type/size tires, big offroad tires will kill your mileage. I have Michline LT X Radials. Great highway tires and light offroading. Gradual start/stops, use cruise control whenever possible, KN Air filter, Full Synthetic Oil helps reduce friction therefore helps mileage. Do not carry a lot of extra weight if not needed. I getting average 18 MPG in mixed City/Highway driving. Straight Highway I would get over 21 MPG. This is for a 2000 GMC Jimmy Diamond Edition.

lol Yeah you have one that I could buy for under $10,000?? Them things are expensive!!

I know there are a lot of other posts, one of them is all about the person's grammar, and the other one is all about CAI.

On that note, would an after-market intake help at all? I've read up that it can get you like 1 or 2 more mpg, but every little bit helps. Brand new K&N intakes are like, $300. What about the ones all over E-Bay for like, $60?? Maybe one of them with a K&N filter??? I don't know I'm just throwing out ideas here.

My blazer did the same thing turns out it was the fuel pressure regulator, you can buy one from autozone for around 45. Be careful when installing it though there is a tiny screw that goes into the top and if it isnt done perfect it will run really rough and not want to stay running but it is also a good way of knowing its not in right. Smell and roughness should go away instantly if done right and gas mileage will significantly improve. I replaced fuel regulator, air filer, fuel pump, fuel fliter and screen as well as a gas treatment and new plugs but did all the later before regulator in narrowing it down. Luckily I have an uncle who is head mechanic at local chevy dealer and when nothing else worked I took it to him. Getting about 17-19 mpg around town now.
