Suspension issues and Fuel Economy

I am curious as to whether leaking struts, and a suspension in need of work would have much affect on FE?

A fellow frugal gas user had some squeeking noises from his '95 Civic, and 3 of 4 struts were found to be leaking after examination. He just wants to live with it for now - $900 fix for all 4 - and wondered whether it would make the gas mileage go down if left as is? (Car has good LRR tires and a recent alignment)

Re: Suspension issues and Fuel Economy

I know if your shocks go, when you step on the brakes, the rears can sometimes skitter, as they become light and leave road contact. I imagine if the car balloons up and down, that aerodynamically on the freeway, it could create turbulence and slow your car down. In city driving your forward inertia can be directed up and down, consuming energy between shift surges.

So does old shocks burn more gas, yes, but I imagine only by a percentage, will 900 bucks worth of suspension pay for itself, probably not. During a panic braking and swerve event, avoiding an accident, the suspension will pay for itself though.

From somebody who's has crashed, its better not to crash.

Plus new struts can extend your life of your tires.

I agree with the statement above that you will see a very small amount of improvement in FE old verse new.

Re: Suspension issues and Fuel Economy

$900 in shocks will save $2 in gas. It'll also make his several hundred dollars of tires last more than 10k miles. I've seen new tires destroyed in less. Used to work in a shop that did tires and suspension and at least every month somebody would come in obviously needing struts/shocks (from tire wear and leaking) get new tires and ignore us telling them they need new anything else... just a few weeks later they're back wanting warranties they can't get because the tires aren't the problem, the car destroyed them.

The question is how long is he planning on keeping the car, if it's being kept till it's not worth fixing, get the struts. If he doesn't want to put money into it: tough. I don't consider replacing an old car with another old car cost-effective because usually unless you're spending as much money in getting a newer car, the replacement old car needs as much work.

Re: Suspension issues and Fuel Economy

Eventually, any vehicle arrives at the point where the cost of maintenance exceeds it's worth.

If the vehicle is paid off the return on investment is different than one being paid for.

Time to do some arithmetic.

Re: Suspension issues and Fuel Economy

Yeah, I agree about the cost/benefit idea with the struts -- and added to that, the excessive wear on the new tires might sway his decision too. Guess it depends on his commitment to keeping this car for the long haul.

It IS paid for, but $900 into a vehicle that he could probably get $2000-$2200 if he sold it is seen as a pretty steep investment right now. However, with gas prices on the rise, it sure is a good FE car to have in the garage!

Re: Suspension issues and Fuel Economy

Does it really matter what he can get for it if he sells it? Wouldn't the more important figure be his cost to replace it (including sale price of old car and purchase price along with repairs required of replacement)? If he wants to buy a similar car with newer struts it's going to cost a LOT more than his old car sells for...most people never replace struts that aren't broken in half.

Re: Suspension issues and Fuel Economy

just buy aftermarket struts and put them on. I paid around $200.00 for the struts (plus another $200.00 for the springs), plus $30.00 for a pair of spring compressors. It took an afternoon to change the springs and shocks on all 4 corners on my '95 VX.

You may want to grab some extra lower mounting bolts, though, if yours have never been out. I twisted one quite a ways getting it out.

Re: Suspension issues and Fuel Economy

Ah my secret dream...to have a male friend who is actually a mechanic! (or at least mechanically inclined) This guy can barely screw in a light bulb correctly -- so although it's a great suggestion to DIY the struts - it's just not gonna happen.

Re: Suspension issues and Fuel Economy

Which is why God made mechanics.

Ask which mechanic your friends, associates and acquaintances, which mechanic they would recommend to their sainted mother in-law and grandmother.
