Good evening BITOG world, I'm about to embark on a project to resurrect my brother in law's 1983 CJ7 Wrangler Laredo that has been parked for almost five years. Has been in the family for over 20 years and it's time to move it on to a new owner. Parked in Phoenix, AZ so a good climate for...

Oil change today on the '77 F-100, ran Rotella T4 10w30 and Napa Gold for approx 1500 miles, 23 months. Long road trip after the oil change back in 2023 then short trips since then. Picture of valve cover from a week before the oil change as well. Light sludge or residue, but it wipes off...

Oil change on the 2022 Yukon XL 5.3L today. 33k miles, last changed at 27k w/27% left on the OLM. Obviously, I'm keeping a close eye on things with the known lifter failure issues on the AFM/DOD 5.3s. Pleats looked quite clean with a few tiny sparkles. Posted both sides of the filter, I...

Cut an oil filter apart for the first time after the 160k oil change on my Mazda6. No issues with the engine or car at all, just curious. This is what I found, quite clean with specks of carbon. From what I'm reading, this is totally normal. Posting up here for any comments. I could not...

Recently changed out my Mazda6 MT gear oil from stock to Redline 75W80 API GL-4. Original oil was still performing fine, but with a hint of notchiness. Old fluid drained out fine, slightly brownish color but no particulates that I could tell. Used this tutorial...

Took the '77 F-100 in to get the AC system swapped to R-134. Long story short, shop read the conversion table wrong and put over twice the correct amount of R134 into the system. The compressor locked up and the belt squealed, pressure went off the scale. Good news is they were able to pull...

Any of you all watching this YouTube channel? Claims of 26 to 41 mpg improvement after putting a lawnmower carb on a V-8. Also featuring the least precise mpg calculations possible ... apologies if this has been posted before. What's really funny is the comment train discussing the vapor carb...

New '22 5.3L Yukon XL owner. Got 2k miles on it, should I use my free oil change now or wait till 5-7k miles? Pros of doing an early OCI on the first one?

Greetings BITOGers, I'm about to take delivery of a 2022 Yukon XL, and I wanted to ask your advice for break-in procedures. Starting out with what the manual says: The vehicle does not need an elaborate break-in. But it will perform better in the long run if you follow these guidelines: -Do...
