Greased lightning

[rabbitman]

Anyone ever use the oil additive they make? One guy told me I'd get 60mpg if I used it and claims his '80s chevy 350 gets 22mpg using it.

Don't use it. Whoever you spoke to is wrong. Modern oil is advanced enough and has millions of $ in R/D that you wont be able to improve it by dumping some other goo in it.

If it needed that goo, it would have it.

That would be fairly poor MPG for a C4 'Vette at 55-60 with any kind of oil.

my grandpas Vette was a 56, and got better economy than that!!

thats what i was thinking, 22 in a fiberglass bodied car, thats not right!

if it gets 22mpg with GREASED LIGHTNING, then i would guarantee that it probably gets 22mpg WITHOUT it also! lol..

Well then your grandpa had the Mobile Economy Run edition Corvette. Almost none of the cars in the '50d and '60s got 20 mpg, but 106 octane gas was $.24.9 a gallon so nobody cared. A Chevy 6 in a Nova was working to get 22 mpg. Not that you could not make one get that with leaner jets and taller gears, but what fun was that? Besides you lost your "power to pass" as my grandpa always told my grandma.

That's why adding more gears has been popular since 1982?
I put an ROD 6 speed in my friends '59, and even with 4:56 gears, it was under 2000RPM on the freeway.

Along with tighter control of the mixture and knock sensor controlled ignitions, reductions in rolling resistance like radial tires and vastly lower Cds.

Well I never said it was in a vette, shoulda clarified this is a k1500 or k2500......can't remember which.

dude, really?

a car that weighs less than 3000#s, thats REALLY aerodynamic, with a TINY 4.3L v8, and a SMALL rochester 4V 4bbl carb, dual exhaust, 3 spd trans, and 3.27:1 r&p gears...

give me one good reason this car WOULDNT get better than 22 mpg? all that equipment i just listed right there, should by all rights and means, get more than 22 mpg, if you dont drive it like a COMPLETE IDIOT..

hell, my cousin has a 94 chevy 1500 4x4 that gets 25 mpg 22mpg REGULARLY.. he dumps nothing in it, and its even got pinion bearings talking.. truck is a THROTTLE BODY INJECTED VORTEC 4.3 v6. (yes, it IS a TBI injection system, on top of a VORTEC 4.3 long block, factory, VERY COOL, and it has LOTS of power, more power than the TBI 350s in his last 2 90s chevys)

anyways, that truck ALWAYS gets 20-25mpg.. seen it myself, even done it myself.. i was in possession of the truck for a week, and only filled it once, didnt even burn all the fuel, and i drive LOTS..

my dads 65 chevy biscayne, with the original 235 I6, he claims would get almost 30 mpg!

[Toby]

Yeah, really. I was around when these cars were new. None of the V8 stuff got 20 mpg. They just did not. None of the sixes got any where near 30 mpg. No matter what your dad says. Also I doubt that a '56 Corvette came with 3.27 gears. That was considered the tall gear set back then.

[R.O.R-2.0]

well, since you cant take my word for it, maybe you can read the same article i did...

http://www.corvette-mag.com/issues/58/articles/the-real-mccoy?page=2

its in BLACK AND WHITE.. read about the 3.55 stock gears, and OPTIONAL 3.27 gears..

why does EVERY SINGLE THING you say have to be an arguement against something else?

my grandpas car DID get ~20mpg. either believe it, or dont believe it, i dont give a gram of F*CK either way..

oh yea dude, your VW diesels DO NOT GET 50 MPG!

dont let anyone tell you otherwise, because i was alive when these cars were NEW.. because it was ALMOST IMPOSSIBLE for these cars to even get 40mpg!

see how dumb that sounds?

just to stir the pot:

we own a 1963 olds F85 (215 V8/4spd trans) and it gets OVER 25mpg.. verified by GPS.. but thats probably impossible also, huh?

(gotta baby it thru the whole tank to get 25mpg tho)

[rabbitman]

So who's gonna "win" this argument? One guy says no the other says yes, whoever's the most mature will shut up first.

So greased lightning is out then, but the temptation to try it remains..........

[theman53]

I would give the greased lightning a try if it won't do anything to your engine harmful. I like the sheaffer's oil, but I really don't think the oil will make a huge difference either way. If you change everything over to synthetic it seems to really help, but maybe only 3mpg...what I have found.

[shwak23]

This should end your temptation.

ok, I must say this,

had an 07 prius, wife got 52-54 mpg on her normal daily trip too and from work, If I drove her, I got 76. WAY better then EPA rating. And Im talking a full week of driving with an average per the onboard computer of getting 76mpg and trip meter to tank fill confirmed. and I could duplicate over and over. believe it... or not?
