That graph has been around for awhile and still cant understand why people still use the K&N junk filters, yeah they flow better then stock filters cause THEY DONT FILTER DIRT AS GOOD, I wouldnt put one of them in my truck if they were free, theres nothing better then the stock AC Delco filter in filtration. I have said this before a buddy of mine ran a K&N filter in his truck and after a few months he removed it and found dirt and sand on the inside of the air cleaner assembly just as it goes down into and around the throttle body, he then put the oem filter in and never had the problem with the dirt.

      OCI, not when but why?

      My post above is the direct reason for my outsized interest in keeping what I have for as long as possible. My memory isn't as short as some.

      I don't think so. 😏 Cars? Our experience will diverge there as well. I was buying cars with 200K (1970's) when I started and quite a few were pretty solid cars. (My early stuff was 1964 to 1968)  Some stinkers but not the dismal picture painted above. Now that said, yes, a dealer wouldn't talk to you if your car had more than 60K on the clock and lot cars were 60K or less except the back row where 100-120K was the auction bought for dirt for us poor losers. Kids in my county were not allowed to wear long pants if they couldn't rebuild and repair every part of that beast.    I will agree that many parts are now better. Alternators and charging systems are an envy. But I replaced few water pumps or power steering pumps then. Rebuilt carburetors but replaced few. Mufflers are another place of OEM improvement. Stainless? We didn't have no stink'n stainless.    As long as humans are in charge of governance this $$$$ situation will not improve.    The purchasing power of a dollar in 1955 is significantly higher than in 2025, meaning that a dollar could buy more goods and services in 1955 compared to 2025 due to inflation over the years. For example, what you could buy for $1 in 1955 would require approximately $10.50 in 2025.  Calculator.net inflationtool.com   Comparison of Purchasing Power: 1955 vs 2025 The purchasing power of a dollar has changed significantly from 1955 to 2025 due to inflation. Below is a breakdown of how much more money is needed in 2025 to match the buying power of a dollar in 1955. Purchasing Power Overview Year Equivalent Value of $1 in 1955 1955 $1.00 2025 $10.50 Key Points Inflation Impact: The value of money decreases over time due to inflation, meaning that the same amount of money buys fewer goods and services in the future. Example of Inflation: What could be purchased for $1 in 1955 would require approximately $10.50 in 2025. This illustrates how inflation has eroded the purchasing power of the dollar over the decades. Understanding these changes in purchasing power is crucial for financial planning and assessing economic conditions over time.  Wikipedia Calculator.net

      The thermometer has been in my wife's 2008 envoy, my sons 2016 chevy, my friends 2020 1500 silverado all showing cooler readings. It's not the guage.

      Trim level custom/pro

      By Gary Doolin · Posted

      Have a question concerning trim levels. Ive not bought a new vehicle since 2006, and I have decided on a 2500 gmc pro or silverado custom. For anyone that has one of these 2 trim levels have you regretted not stepping up to the LT or SLE. I look at things as the more electronics the more problems to arise. I love the look of the old school gauges on the dash as well. Looking forward to hearing your thoughts.

      If that guage has a way to adjust [hex on bottom], put that thing in a glass full of ice, put water in, put your gage in, let it sit for 3 minutes or so, and set it to 33 degrees.
