Auto maintenance pro. And my excel spreadsheet as a backup

The ONLY correct answer here is to contact BF Goodrich and have them determine the proper psi based on a load chart conversion for that Specific tire. My Tahoe came with a P rated 265 @ 35 psi. BFG recommended 50 psi based on the 3 load rating comparison / conversion. My Goodyear Duratrac...

I had to get a rear main seal and the upper/lower oil pan gaskets changed on my 02 Ford Explorer 4.0. The vehicle has 101k A lifetime of M1 and Pennzoil Platinum have served it very well. The vehicle mostly sees short trips and yearly mileage ranges between 4,000 - 7,000 miles/year. The oil has...

I have an 05 F-150 4x4 V8 as a company vehicle. It has 140k on the clock and runs perfectly. It has thousands of hours of idle hours on it. There are days once I arrive to the job site, it will idle for 10+ hours, then a long drive home. It has done this since the day it was given to me with 5...

My bet is they topped the oil off when be bought the vehicle resulting in better additive/tbn numbers????

Alright guys, he got the oil sample back today via email. This oil by looking at it had well over 5k on it. It was black as could be, the filter was awful. To freshen up everyone's mind and to make a few corrections to my original post 2007 BMW 328I 3.0 v6 Oil is BMW Mobil 1 @ the dealer...

Averages around 75-80 miles a day since Jan. Drives it 1-3 times per week. City driving, occasional hwy.

[ADMIN NOTE]: There is a UOA report in this thread, it's just down in the third page... My neighbor came over this weekend and asked for a hand changing his oil & filter in his 2007 BMW 328 sedan. He took it to the dealer for an oil change (was going to pay the $150 for it) and they would not...

Found some Pennzoil Yellow bottle, swapped it out and and we'll see what the next OCI does.

The 04 I had posted using the M1 ran high numbers then leveled off. This 07 has had a spike as you can see. Some is from the GTX itself but I'm now starting to wonder whats going on. This past OCI was about 80% city driving, VS 95% hwy on the others. I hate to but maybe I"ll drain the GTX and...

Here's a report from my 2004 HD 6.0 (Same motor,etc) running M1 5w-30. Maybe its wise to change the oil to a different brand?
