This is probably gonna open a big can of worms.
I’ve got a 96’ Taurus with 201,000 miles. I may want to replace it, the whole car. It has been idling rough lately. Can that sometimes be an indication of worn timing chain or EGR valve? My check engine light is on, and I think it’s something to do with the EGR system. Anyway. Deviating from original topic.
With that being said, my taurus gets 24-26 mpg average. Is that normal or below normal. I’m disgusted by the mileage. Long story short my morning commute is 4 blks to county highway and 55mph on county highway for 12 miles, then 70mph for 30 miles and about 12 city blks until I arrive at work. If I drive all posted speed limits I might get 24 give or take. If I drive 60mph the entire way (cept for city of course) I might avg 26mpg. As an experiment I drove 45 mph on an entire tank and got 30 and no better than 30 mpg. I used to have a '92 Mustang GT 5.0 and got 23 mpg (there were alot of variables in that situation) I was impressed with that mpg. I talked to a guy at a gas station that had a 2000 (i think) F-150 supercrew with a 4.6L. I asked him what his best tank was. He said he doesn’t get to take it much out on the highway since he lives in city but his best tank so far was 24 mpg! I wanted to push my Taurus in the ditch!! I don’t think he’s far off. My wife drives '99 Expedition and we’ve gotten 20mpg going 70mph with AC on to Nebraska.
Was that guy pulling my leg though?? If not, I want something MORE comfortable. I’m 6’ tall and 30 pounds over weight and approaching the end of my life span at 30 years of age. I would like to be more comfortable if I get RELATIVELY same mpg. I’m really eyeing the 4.6L for that reason. I would like to still have V8 since it is a truck. I drive about 70 miles a day round trip. I do not have a problem driving slower (not slower than 55 though).
In the aforementioned truck I would like to look for, can a person change the ring gear in rear end for a lower ratio?? I’m not sure what’s factory and I’m not sure what ring gear my wife has in her truck. Would a lower ring gear ratio help lower rpms on highway by just a little bit?? Or does changing ring gear seem like a circle, making the engine work just as hard to get up to speed, thus defeating the purpose? You would think the engine would work at a certain rate but once at highway speeds the ring gear will make the difference. hmm, anyway. I’ll do whatever it takes to imprive fuel economy. If it can stay close to economy of Taurus, i will be happy as a tornado in a trailer park. Would that be possible? If you own one of these trucks give me all the info/opinions you got. If your friends have one, ask them (preferably not after 6 beers and during nascar).
MY NEXT QUESTION IS VERY IMPORTANT:
I know this is cliched to say this, but, “I have this friend…” I went to high school with. Him and his dad are big ford nuts (i am too, that’s all we own). He works on alot of cars on the side to help friends. He personally doesn’t like the Triton motors in these ford trucks/suvs. He thinks they’re a poor design. The biggest thing he was warning me about is that these motors like to blow spark plugs, thus stripping out hole. He cited 2 or 3 examples of guys in town that have had those problems, not just 97-03, but 04-08 as well. Like I said, my wife has '99 Expedition and we’ve never had issues like that. Course, my wife is the greatest driver I know! She babies that truck. Okay, now for the question: DOES THIS HAPPEN? HOW MANY CASES? (RARE?) SHOULD MY MOM BE CONCERNED WITH HER 2002 LINCOLN CONTINENTAL??
I think that’s all I wanted to post. Thank you in advance!!! While I am open to and you are entitled to your opinions, I am partial to Fords. please keep ford slams to minimum. The best one I heard was “ford figured out the problem and circled it!” (refering to emblem) an old timer told me that.
