What would be a better gas to run in an original 1959 MEL 430 motor with 10.0:1 compression? 87 ethanol free or 91 with ethanol? Use will be more cruising than racing.

Depends on what the fuel system is made of. Cars that old weren't expecting ethanol and used stuff that doesn't play well with it. Some types of rubber in gaskets, and zinc in carburetors, particularly.

On the other hand, leaded regular was 89 octane, so you need higher octane without the ethanol (until you know it's safe, anyway). 87 is probably OK, but I would recommend 87 pure gasoline with a safe octane booster.

I had a '59 Edsel for a while and that's what I did, anyway.

Wait, when was leaded fuel banned in America? Google says 1996, but that can't be right, can it?

Maybe I'm not asking the right question, when was it common practice to design cars in the NA market to run on unleaded gas?

Unleaded gas started appearing in the mid 70s, as automakers chose to install catalytic converters to cope with tightening emissions regulations.

Low power / no-turbo Golf chat continued...
I took the Golf over to my dad's today to have a look at it.

Well, we found the actuator, and it was jammed. I could just barely jiggle it to get it to move.


So we took the EGR valve pipe off, and look how cruddy it is!


Stupidly though, we couldn't find oven cleaner that had a pipe that fit into the nozzle, so we couldn't rig it up to a longer, flexible hose like in the videos we found online.
We put some oven cleaner in the EGR valve pipe and blew it in with a vacuum. I may have caught some oven cleaner in the face on the first attempt. Goddammit. (we both had goggles and gloves)

More pushing on the actuator, and now it moves! Probably pretty close to 3/4", but not easily. It's still very stiff. I think I detect a slight increase in power when driving the car, but not a significant amount. We might try another round of oven cleaner tomorrow, since it was fairly easy to do and now we know the procedure. Is there anything else we could try?

Oven cleaner probably isn't very effective as it mainly uses lye to dissolve the natural fat residues caked in ovens. It won't do much with petroleum-based goo like that.

I'm not sure what to recommend, though. It may take some manual scrubbing with a toothbrush. Perhaps some WD40 or something like it would loosen it up?

Not deionized/RO though, as that'll pull ions from the metal in the system, and accelerate corrosion, from what I've read.

There's no functional difference between DI/RO and distilled unless you're a chemist and require ultra-pure water.

Unless you have exceptionally hard tap water, there's no actual advantage to using deionized/distilled water. Metal parts will indeed corrode slightly in contact with the water to reach an equilibrium ion concentration, but it's probably not significant. It's why coolants have buffers and anti-corrosion additives.

Thhe reason to use distilled water is to keep calcium/lime deposits (hard water) from building up in the system. I would flush into containers till it comes out mostly clear, then onto the ground till it is completely clear. Then drain fully (may need to disconnect more hoses and/or remove drain plugs and tip the car around with a jack to get it all out) and fill it back up.

E: on the pt cruiser, no the leaking oil is probably not a warped head or bad head gasket unless it is also leaking or consuming coolant. I dunno why you would think that as a parts store guy... also if you put r134a in it, please make sure it is NOT the can with leakstop in it, and if it is one of those parts store refill kits, you may not be doing the buyer any favors because the gauge is pretty bullshit on those.

That's correct. My point was that unless your tap water is exceptionally hard, the total amount of lime introduced in ~4 quarts of water is minuscule. The vast majority of the metal ions that form the carbonate scale in cooling systems comes from the slow corrosion of the internal metal parts themselves. Using distilled water doesn't hurt, but it doesn't really help any, either, in most cases.

Question- I bought a new car, a Toyota hybrid. At the very end of the sales there was a huge discussion of an extended warranty package (7 year and like 80k miles) for about $1500.

The big push of the argument was about how complicated the cars are, how many parts there are, how some basic work like a heater fix took like 20 hours (NOT KIDDING - I hope that I misheard that) to replace.

I declined the coverage but was informed I had 24 hours if I change my mind.

The one's they have at the gas station look like this.

Those are the standard inflation valves that have been used everywhere for like 100 years. Maybe you should learn how to use it.

You push it on, centered on the valve stem so that the valve seals in the hole. When the valve stem is fully depressed it presses on the central button, releasing the air into the tire.

Sheetz has free electronic ones but they are broken like 15% of the time.

Also, is over or under inflation generally worse for the life of a tire or are they both equally bad?

My new car lists 33PSIG on the doorjam and it came from the dealership at about 40. I cut the pressure down to 35. (There was a recent 20°F swing up here too.)

Underinflation is somewhat worse AFAIK. Overinflation makes the tire wear in the center first and leads to a hard ride, but it will still squeeze out water and give decent (if not optimal) traction.

Underinflation leads to wear on the edges first and makes the tire more apt to trap water under it (increased hydroplaning) as well as increasing rolling resistance, which leads to worse gas mileage and higher tire temperatures which wear it out faster.

Between once a week and once a month, I hear a strange noise when I start my car. The sound sounds like the sound when you start your car even though the car is already running. Is it possible that I hold the key in the 'Start' position for too long or is this something else (serious/benign)?

I guess I could just envision getting in an accident, fuel tank rupturing, the flares somehow ignite the tank and I literally die in a car fire. Probably pretty unlikely.

Of course the hybrid battery is probably just as bad potentially. I've also heard that in modern vehicles if you're in an accident so severe that the fuel tank is compromised you may already be dead.

Unless you're driving a '74 Pinto, rupturing the fuel tank is not a serious worry.

I've never had an occasion where road flares would have been even slightly useful, but some sort of LED warning light might be worth considering - particularly if it doubles as a flashlight. You'll probably never be in an accident where you need to warn traffic away in the middle of the night, but you might need to change a tire.

After a lifetime of owning carbed vehicles, my pops is convinced that he needs to warm up both his and my mom's vehicles for crazy amounts of time when it's cold. Even better yet he thinks it's a good idea to just start the vehicles when it's cold and warm them up then shut them down "just in case we need to go somewhere later". I can't get him to understand that modern vehicles are completely different animals, and that all of the electronics in a modern vehicle use a lot of power, which the alternator can't easily supply at idle. He's always having problems starting vehicles when he actually does need to go somewhere, dead batteries, etc, and I'm 99% sure it's because his vehicles spend more time idling than they do driving somewhere. He will not listen to me, but he seems to listen when people on youtube say stuff so maybe I can keep him from hemorrhaging money and tearing up their new vehicles.

Which is why I was so frustrated, the oil threads had so many jokes about lubricating the outside of the engine, but few conclusive answers. Do classic cars need Zinc additives at all?

Probably not. Engine wear comes from a lot of sources, and reduction in ZPPD in recent years may be just a convenient whipping boy for engine builders. I'm not aware of any actual studies or statistics on it, just word of mouth stuff.

The wear area in question seems to be specifically flat tappet lifters. I don't know what engine an X1/9 uses and if it's got them. If it uses roller lifters, you're home free.

In any case, modern oils are probably fine as is. If you're really concerned, you may want to seek out some classic car oil that is specifically SA, SB, or whatever the SAE standard was when your car was made and the OM recommends. Then you're safe. I wouldn't recommend an additive in any case, because too much ZDDP causes excessive wear as well.

Do your studs have carbide cores? Mine do, and have no problem with exactly what you said, I do 180 miles a day for work at speeds from 65 to 85mph depending on the speed of traffic and all that happens is my car sounds like a TIE fighter. They bite fine on ice and snow every morning going up the dirt road to civilization even so. You can tell if yours have carbide cores or not (most modern studs do) - if they have a little center tip that sticks out further than the metal cladding or the rubber around it, they're carbide. Doing a burnout or sliding around a corner will definitely break the carbide off, but it'll be exposed again within a few hundred to a few thousand miles when the metal cladding and rubber wears down around it.

Belts get very stiff and gripless at temperatures that low, so the squealing was just belts slipping on cold pulleys. They should be fine once it warms up again.

Good points, but keep in mind the new car warranty. I assume you'd be grilled pretty hard on a failure of a component that was even vaguely associated with a system where you had installed an aftermarket part.

The Magnuson-Moss Act puts the onus on the dealer to show why your aftermarket part directly caused the failure of something else. They can certainly try to deny coverage, but if you stick to your guns they will usually back down.

For front-wheel drive, I generally put the new ones on the front, since that's where I need the best traction. Radials should stay on the same side of the car once they've been driven - they develop a lie to the belts, and reversing them can cause wrinkling and buckling which ruins the tire.

Bidirectional means the tread is symmetrical and it can go anywhere on the car and rotate either direction at installation, but once it's going one way it should stay that way.
