Re: Automotive myths
My Dad always told me to stick with the same brand of oil when doing oil changes when you buy a new vehicle....I thought it was BS...till a friend of mine changed from always using Quaker State to a cheaper off brand oil....spun a bearing in a 3 year old Dodge pickup with 40K miles.

Re: Automotive myths
^^ That's because of using the Quaker State all that time,I bet. I did the opposite because I was on a road trip to Arizona. Went to a Quik-Lube for a fresh change for the return trip and they used Quaker State. I really didn't like that,but figured any fresh oil is better than the oil that brought me cross-country and through the mountains. By the time I got back my oil pressure was significantly lower from then on. I had been running Castrol GTX. I don't know about now,but in '89 Quaker State was parafin based crap after formulations changed some years prior. I actually stood by Quaker State in my first vehicles in the early-70s,till they changed it.
Hey Slomotion,I guess that counts my vehicles out. My newest is a '92 diesel and everything runs when I'm on glow plugs prior to and during cranking. I can hear the heater fan slow when I forget and leave it on. just an old habit now

Re: Automotive myths
How about the One I used to hear for years on end?
If the auto industry wanted to,,,, they could make a carburetor that would get you 100 miles to the gallon.... but the reason why they cant is the oil companies have bought them off..

Re: Automotive myths
There might be some truth to it. My fil used to get 35 mpg in his 78 civic.

Re: Automotive myths
I think that might be due to what we used to use "Real Gas Made From All Oil,,no corn added..

My '64 VW gets 36.25 highway mileage (60-65 mph) running around 16.5:1 air/fuel ratio, and that's with E10 gas/ethanol blend. Engines won't won't run any leaner than that and still be driveable. No way any engine can run lean enough to get 100+ mpg on a normal car from just changing the carb; the spark won't ignite, or burn fast enough if it does ignite. It gets difficult to ignite over 17:1 AFR. Leaner mixes burn slower, you have to add timing advance to even run 16-17:1.

Re: Automotive myths
Yep! If there was a carb that could give 100 mpg back then,it wouldn't give but 75 on what they call gas today. Same with that Ultra Low Sulphur Diesel. Here's a myth,the reason we have these fuels now is because they are better for the environment. Now here's the fact,they create a larger profit for the oil companies at our expense. Burning more fuel per gallon produces more emissions. No math or science to it,just pure common sense.

Re: Automotive myths
Some years ago I along with others thought that the cars with brains in them( computers we learned to call them) was a terrible invention just so the manufacturers and machanics could control all work done on cars and trucks..
Then as time went by I and others noticed that these computer fuel injected motors did in fact give the best performance you could get.. So the myth that these computer controlled automobiles would fail ,,was just that a myth..

Re: Automotive myths
Diesel Rabbits were getting 50 mpg in the '70s. Now what do the new hi-tech VW diesels get?
There are drawbacks to computers in vehicles. It is possible for a bad intentioned entity to shut them all down. I'm not a paranoid conspiracy theory type,never give it thought. But there are those who feel this is a risk. Then there's that whole black box thing. No thanks big brother. I see all the time people pay good money for repairs that haven't gone away. Even with scanners it's not so cut & dry like the good old mechanical vehicles. Many many many expensive repairs are done when it's some simple little thing. I'd rather pop a rebuilt Quadra-jet on my truck for a fraction of a repair shop bill any day. The new stuff goes and goes for many more miles w/o work. But,when they do need something...gotcha!

Re: Automotive myths
I think the major drawback for a computer controlled vehicle is the claim for the life of the vehicle.Just how long is the life of a vehicle by the manufacturer standards?I have seen to many times when even a good mechanic can not figure out what is wrong with a computer controlled car.I have more faith driving my 72 or 69 impala on long distance trips than my newer vehicles.They don't have a computer or 50 sensors letting the engine know when to get the spark and fuel it needs to get down the highway.

Back in 1988 I bought a new Pontiac Grand Am with the quad 4 engine and 5 speed. It was getting 40 MPG on the highway at 75 MPH. But I did do a few minor modifications to the engine and suspension. At the same time a friend of mine bought the newest Volvo wagon for almost twice the price and he didnt get anything near the gas mileage I got. But I do not think my Pontiac would get anywhere near the same mileage now because of the new formula gas we have. And the gas is going to get worse. At least we are sucking clean air into our lungs.

Re: Automotive myths
Yes some of the early 70s car got very good MPGs. Dad had a Datson B210 that could get 40 or so. My brother and brother in law each had deisel Rabbits. The diesel Rabbit could run on pennies. The one fact that you guys are forgetting is the horribly animic horse power. Pulling out on the freeway was a challenge. High MPG, low get up and go. Those diesel Rabbits were horrible in the mountains.
I do not like to give up drivabiltiy for high MPGS. I comprimise towards the drivabilty side.

Re: Automotive myths
The 60's/70's cars got great mileage because they didn't weigh as much. Now it takes all the modern technology available to get good mileage at double the weight. 1964 VW Bug weighs 1640 pounds, 2014 Beetle weighs 3100+.

Re: Automotive myths
I've always wondered about people who put cardboard in front of their radiators to help their heaters run hotter.
To my thinking the thermostat controls the engine temperature. I think that putting a piece of cardboard in front of the radiator will only risk overheating the engine if the engine is generating too much heat.

Re: Automotive myths
Your dad was correct and by tweeking the carb jets you could get 30mpg and another thing is the V-8's got better mileage with the correct tranny and rear end than the 6 bangers..

Re: Automotive myths
My cousin owns an early nineties ford truck.He paid some one to rebuild the transmission.When the transmission wouldn't shift as it should after the "rebuild" the guy who rebuilt it wanted to put a bottle of sea foam fuel cleaner in it to clean up the sensors on the inside of the transmission.Just when I thought I've heard them all.
