No, you're right to push back on me. I was somehow not grasping the full picture and was thinking more like a higher-hour industrial gas engine that runs a lot of hours. A 0w or 5w is where you want to be, especially with splash lube. Splash lube makes thinner oil at cold start a bigger...

I'm glad it's working for you. With that, I'm out.

This is exactly the kind of overhead where Valvoline Restore and Protect can strut its stuff. The thicker varnish on the unmachined part of the camshaft is where you'll see considerable improvement. The tan varnish will mostly be gone int he first 2-3 OCIs. Even that dirty, Valvoline Restore...

Valvoline Restore and Protect giving good results on that OCI, keeping you in single digit Fe for 5k OCIs is a good place to be.

I don’t find it threatening at all. I’m just annoyed by the cultists.

The OP is kind of absurd because fuel expense is just one kind of expense. it’s about the *total* cost—not the marginal cost of fuel. That means insurance, tires, depreciation, all of it. Not just fuel. EVs make sense of a lot of people. Not for everyone though.

True, there are loads of junk air tools. Anything branded "Coleman" or "husky" etc is basically garbage. THe good news is that good tools don't require a massive step up. You don't need to go from a $40 impact to a $400 impact to get a good one. There are some medium-to-compact impacts out...

Not at all. The vast majority of compressors of that size are nominally 2hp or less and run on 120V. Some--few-- 2HP compressors are dual voltage.

A 20 gallon tank compressor on 120V is right at the ragged edge of what most LVLP setups will need for air (6-8 SCFM). You'd be wise to consider an extension air tank of 10 gallons or so.

That K20C4 was not seized. But it did have stuck rings at mileage in the low 90 thousands. I'm certain that the ring seizure issue is heavily duty cycle dependent. I'm guessing your applications with mostly highway miles never experience the issue. Indeed, we stuck rings on Audi and VW vehicles...

In the past, you had engines making 40-50hp/L. Now you have double that AND then we moved the rings up higher on the piston to reduce emissions of unburned hydrocarbons. As a result, ring packs operate much hotter now. Combine with thinner oils that aerosolize rapidly and have higher temps in...

I wouldn't bet on it.

Meh, I'm sure USAF figured that was the VA's problem.

When I was doing fuel system repair for the USAF, we used MEK to strip fuel tank sealant (the 8802 class B stuff). This was after we scraped most of the sealant off by hand. The residue we would then attack with brushes and MEK. In an enclosed space, it's a compelling case for a Scott air pack...

the jungle, believe it or not. But here's the intriguing thing about it. The email tracking listed it as an "office supply." ANd the return address? The "global climate alliance" of merrimack, NH. You can't make this stuff up.
