Here’s the second oil change on the new engine from my Tundra. Total vehicle mileage was 36,102 miles. It looks like break-in is going well, silicon definitely had a large drop on this change. Thanks for taking a look and any thoughts are welcome!

Hey all, this UOA was the factory fill w/795 miles from a new long block installed in my Tundra earlier this month. I thought I had read that TGMO had reduced the moly content, but at least this sample still had high levels which was surprising/nice to see.

This came off of my 2022 Tundra 3.4TT that recently had a new long block installed under recall. This was the factory filter with 795 miles on this OCI.

Here’s the filter from the last OCI on my F-150 5.0 before I traded it. It had 7,435 miles with HPL P.P. 5W-40, this was the second run on HPL with 2k of HPL E.C. 30 on the run before that. I was amazed at the amount of carbonaceous material that was in the filter given this truck had quality...

Hey all, I just bought a ‘22 Tundra with the 3.5 twin turbo iForce engine and was wondering what others have been running in this engine? Right now it has fresh dealer bulk oil in it, presumably Kendall 0W-20 as that’s been their bulk oil for years. I’m leaning towards running 5W-30/0W-30 of...

Hi all, I’m looking at purchasing a 2022 GMC Sierra 1500 SLT with the 6.2 v8/10 speed transmission and was wondering what people’s experiences have been with the current gen as far as reliability, likes/dislikes, etc.? How is the 6.2 for fuel dilution and carbon deposit issues, also are lifter...

Hey all, I’m getting ready to change the transmission/rear end fluid in a Farmall H that I just acquired and was wondering what people’s thoughts are on GL5 rated 80W-90? From what I’ve found it originally called for straight 90W gear oil. I wasn’t sure if there is anything in GL5 rated fluid...

Hi all, here’s the UOA from the third run of Schaeffer’s Supreme 9000 in my F-150 5.0 V8 with 125k miles. So far I’ve been really impressed with the results that Schaeffer’s has been returning, but at the same time I’ve been thinking of ordering some Schaeffer’s Euro 5W-30 Full SAPs to try 😀...

Hi all, while searching for some parts in an old warehouse/shop today I found a quart of CO-OP branded engine oil. It was rated API SF and SAE 10W. There was also an old oil spout sitting right next to it, which I forgot take pictures of. As a side note, the COOP brand was Farmland Grain (a...

Hi all, here’s the latest UOA on my F-150 5.0L V8. 7.3k miles and 4 months on this OCI. The analysis came back looking good minus a touch of fuel dilution, which could have been because I only drove the truck 2-3 miles to warm it up before the oil change. This is the new API SP formula, and the...

As the title says here’s a John Deere filter cut open with unknown hours and time on it. This came off of a Kohler CH20 on a Miller welder with 1238 hours on it. Judging by how low the oil was (barely touched the dipstick) I’d say it’s been on there for a long time. There was a considerable...

Hi all, I just got a VOA of Kohler’s syn blend 10W-30 here, and I was curious if anyone knows who manufactures it for Kohler? Thanks in advance!

Here’s a VOA of Kohler’s synthetic blend OPE oil. Looks to be a pretty stout oil.

Hi all, here’s the latest UOA from my dad’s Lincoln Mark LT (F-150). He ran this with a Napa Gold filter. Overall, it looks like Napa/Valvoline oil has a pretty decent add pack to it.

Hi all, here’s the latest oil run from my 2013 F-150 5.0. A little background, from 30k-104k miles this engine saw nothing except P.P. 5W-20. I got a wild hair and decided to go full BITOG and change things up, both brand and grade! This oil was in service for just under 4 months and saw...

Hi all, I purchased a new Cub Cadet XT3 this year with a 22.5hp Kohler Command Pro and was curious what everyone’s thoughts are on what I should run for my next oil change? The dealer gave me 2 quarts of Kohler syn blend 10W-40 and a filter when I purchased it, which I used at 25 hrs. I...

Hi all, here's the first UOA that I've had run on my 13 F150 5.0 with 45,365 miles at the time of sample and 5,809 miles on the oil. My driving is mostly short trips (less than 15 miles/day), with ocassional highway driving on weekends and a decent amount of driving down dirt roads. This was the...

Hi all, here's the latest Blackstone report for my 2004 F-150. The oil had 6,790 miles and 2 months 10 days on it. I changed out the old oil and filter with the same combo, more QS Defy and a K&N oil filter left over from the Pennzoil special's a while back. I also changed out the air filter at...

Hi all, here's some pictures I snapped yesterday as my dad and I changed the valve cover gasket on my step-sister's 1997 Toyota Corolla 1.6L engine. It's been leaking and burning oil since she bought it so we changed the VC gasket and PCV valve to help slow it down a bit. It's heavily varnished...

Hi all, I was hoping to get folk's thoughts on whether these plugs look acceptable for 55k of use, and more specifically about what would cause oil to get onto the plug from the #5 cylinder. These plugs came out of a 5.4 3V Ford with 164k miles. Not all of the plugs are pictured, as one had...
