So the same thought I have behind Seafoam. As in, it would be a million times better to clean manually, but a light petroleum solvent running through can do a lot by itself, especially in an engine that is hard to open up (like a lot of 90's cars) is better than nothing. I love how when I first seafoam'd my dad's 83 Ranger it made a gigantic black cloud, but subsequent seafoaming created nothing except the white cloud of the seafoam itself burning.

Induction service is legit-ish; I feel more indignant over stuff like a $180 headlamp polish that pays half an hour and uses $7 worth of tiny one-shot stripper and sealant cups and a paper towel.

The real fuel system cleaning setup is pretty fancy. It's not just suck it with a vacuum line like with Seafoam. The tool is like an IV drip, you hang it from the hood latch, dump the bottle of magic in, and set it to drip over the course of like 30 minutes of idling. Run it through too hard and you can cause the car to bog down and throw codes!

Take out out on the interstate get it good and hot, and add a pencil stream of water in the intake at about half throttle and it will flake all that carbon off. ( last one I did this on was a TBI Chevrolet, don't know if i would on modern stuff) works well for tractors too

I've had moderate success with 'ac delco combustion chamber cleaner' which, as far as I can tell, is the equivalent to seafoam in an aerosol can. Spray it in a convenient vacuum line while keeping the revs above stalling, then take the car for a blat and watch the magical bus-sized cloud of smoke come out. I've had this work on both GDI engines and gummed up conventional lumps.

cursedshitbox posted:Why would that be? for curiosities sake. Not Shell, but I have heard that Texaco (Chevron) gasoline caused sludging in certain Saab engines (B205, B235) because of certain contaminants, the dealers told people to avoid this brand and of course GM was sued into orbit in the early 2000s to stop telling people this. The problem was fixed in the end by modifying the sump ventilation system (mod 6), but black sludge remains a very stubborn concern to this day with people who stubbornly keep driving Saab (ha!)

Inconsistent composition between samples, stuff like the API specific gravity varying more than it should, dirty engines when other brands don't get filthy, etc. I don't remember all the specifics because I was drunk at a party when this came up and a graybeard started his own rant about how he got the lab to stop using Shell gasoline for their gas engine tests. They test oil formulations under varying running conditions, they probably know their poo poo.

Have any scientific tests ever found meaningful differences between brands of gas? A number of media and consumer organizations have paid for tests that found no differences, which is consistent with what we know about the fuel industry, so it doesn't seem reasonable to put much stock in rumors from friends-of-friends.

I don't really think so. I did talk to a guy who analyses fuels for a different purpose (arson investigation) who said that generally they were indistinguishable chemically, though you could tell what region they were from because of the different additive requirements. I have heard that techron is actually legit, but you need to add more than cheveron ads. The biggest difference is in cleanliness of tanks and the like.

Shell owns their own refineries, similarly the brand I prefer, Valero, does too. There are definitely quantifiable differences between brands: I once had a job which included access to refinery lab data as part of software troubleshooting requirements, different brands have different specific gravities, vapor pressure, flashpoints; not huge differences, as there are ranges they need to be in, but this was also close to ten years ago. I would like to see the methodology that any news studio used, because I wouldn't be surprised if they ended up testing the output of just one refinery and didn't know what gas station chains used different refiners/additives. You're going to burn thousands of gallons in your car's engine, minor differences will add up. Part of why it's hard to get an aircraft type certified for road gas is due to the varying quality of road gas, especially concerning vapor pressure. The petroleum industry knows how to tell them apart, for sure, and it's not just the additive packages.

EightBit posted:Shell owns their own refineries, similarly the brand I prefer, Valero, does too... From a practical standpoint, none of this matters at all to a consumer since your whole post relies on the assumption that a particular brand of gas comes from a refinery owned/operated by that particular company. Just because the gas station says "SHELL" on it doesn't mean the gas was refined at a Shell refinery. Retail fuel marketing is generally handled completely separately from refining. A town might have one fuel terminal facility (where the gas stations buy their gas wholesale) that serves several different brands of gas station. Generally speaking, the only difference between two different gas station brands in a given area is the additives that the terminal adds to the gas at the point of sale. I've put together SPCC plans and FRPs (federal oil spill prevention plans) for terminal facilities that stock additives for half a dozen different brands of gas like Chevron/Texaco, Amoco/BP, ConocoPhillips, Sinclair, Sunoco, etc. These things can typically serve dozens of gas stations for a relatively large area, and may get their gas from a refining company that you have never heard of (to name a few of the ones with less brand name recognition: HollyFrontier, Flint Hills Resources, Western Refining, or any of the other small private refiners that dot the country). The tl;dr is that you really shouldn't put too much weight on the brand you're buying if you're worried about the quality of gas that a particular company's refineries put out, it's all mostly the same stuff in any given region (minus the additives).

It had been having the issue for at least a year though before my mom finally asked me to take a look at it.

FatCow posted:Too bad they all pump their gas into the same pipelines. This. My brother worked at the Richmond CA refinery. The gasoline delivery trucks with the different brand names all pump from the same tanks at the refinery. What additives are done in addition are where the differences lie, but fuel quality and additive amount is so tightly regulated that it doesn't matter anymore. 20 years ago that wasn't the case, but with air quality management being what it is at least here in CA it all comes off the same spigot. Googling around doesn't reveal much real information about it either so between that and the security measures (like no cell phone cameras) at the refinery I'm inclined to believe it's part of oil companies controlling market perception rather than anything substantive.

This was in Minnesota which sources most gasoline from like two refineries. Out of state fuels with different blends were pretty recognizable and when one refinery went to a newer blend sooner than the other, it was noticeable.

Usually the ball bearings getting out of the pulley go into the belt causing a jump long before that one comes off. Also, did the pulley melt a hole in the timing cover? That's another classic failure mode of those.

And that is why you should always replace the idler pulleys (and water pump, because you're in there anyways) when doing an EJ timing belt. Oh, and the tensioner. And the goddamn cam seals... and crank seal.
