Here's the final UOA for my '08 Civic Si Sedan. This car was a joy to own, drive and modify but we had our fourth child last fall and my business keeps growing so I needed to make my 4Runner my daily driver, work truck, tow vehicle, etc. and bought a 2014 Honda Odyssey as the main family...

Here's the analysis for my 2007 Toyota 4Runner V6 4x4 (A750F) transmission's factory fill of Toyota WS ATF. This fluid only had about 300 miles of towing near MGVW with ATF temps reading up to 240F on the steep sections of my trips but did have probably a dozen or two hours of off-road...

Here's the latest UOA on my 2008 Civic Si. I've continued to make minor changes to the ignition timing and have seen knocks counts drastically reduced but it finally clicked that when I was tuning and running on the dyno my torque numbers were about 25-30% above a stock motor and therefore the...

I've been trying to figure out where a small amount of lead had been coming for quite some time. In the fall last year I started looking at my Hondata data logs and was logging a lot of knock. I started tuning the ignition curves myself until this was completely fixed and then in December I...

I discovered a tear in one of the rubber couplers on my intake about two weeks ago while under the vehicle. I had noticed that my intake air temperatures were reading high on my datalogs (I tune and datalog with Hondata's Flashpro). Intake air temps were on the order of 30F above ambient vs...

Here's the used oil analysis on my '07 1GR-FE 4WD. First sample was standard Mobil 1 5W-30 that the previous owner had been using for every change since the truck was new. I went ahead and wanted to see how a 5W-20 from a similar class of oil would perform so when I did my first oil change I...

This is my first run with full tuning of my bolt-on mods with Hondata's Flashpro. The engine was run very hard for the better part of 3 hours on the dyno when it was being tuned with dozens of runs under full load from 1500 RPM all of the way to 8500 RPM (fun is programmed to stop at 8600 RPM)...

Here's the first used oil analysis for my 4Runner purchased used back in November. The dealer paperwork that the owner had showed that it was and has been filled with Mobil 1 5W-30 and it had the Toyota oil filter. I pulled a sample through the dipstick tube so I'd know how much life was left...

I posted this on a Toyota forum I frequent but figured it belonged here more than there. Back in '09 I posted the results of the UOA at 125k, having a hard time believing that this truck made 10k on dealer bulk. Here's the far more suprising follow on. Enjoy...

Here's my latest UOA for my 2005 Honda CR-V. The first 4500 miles of this run were covered over two weeks on a road trip from California to Alabama with stops in between and the end of July through early August. I knew these miles would be relatively easy on this engine so I figured I'd go about...

Hi folks, I just received my UOA back from Blackstone and it's leaving me with a bunch of questions and some homework on my part. This was the result of the third oil change on my 2008 Civic Si using Pennzoil Platinum 5w30 and a Purolator PureONE. The maintenance minder was at 5% when I dumped...

Did a buddy of mine a favor and changed the oil for him after almost 10k on dealer bulk dino and expected to see some worn out oil come back on the UOA considering how this vehicle is driven (lots of ~3 mile short trips on cold starts). See my thread asking for advice regarding this truck here...

Here's the second batch of oil that's been through this engine. I replaced the factory fill with Pennzoil Platinum 5w30 and slapped on a PureOne filter. I estimate that the engine consumed approximately 1/3 quart. This OCI included some work on the dyno with the Hondata K20Z3 Reflash that now...

Howdy, A good friend and coworker of mine and I were chatting maintenance and oil analysis for a few minutes at work and he mentioned he picked up some oil to do a change on his 1998 4-cyl Tacoma 5-sp and was thinking of taking a sample for a UOA. He said he wasn't sure the last time it was...

First oil analysis done on my 2005 Honda CR-V EX 4WD Auto. The factory warranty had just expired (due to time) and I wanted to make sure there weren't any issues since I had to add a few cups of coolant over the past three years (can't find any leaks). This vehicle is almost exclusively used...

This is the first oil analysis done on this car at just under 102,000 mi. I'd owned it since new and sold it to my brother earlier this year. Back in June we met up and did some preventative maintenance on the car (hoses, coolant, plug wires, cap, rotor, check and adjust valves, check the timing...

Like the title says, this was the factory fill on my 2008 Civic Si pulled at 4146 miles. One of the main reasons I made sure to take a sample and send it in was the fact that I had cracked open the intake manifold to add an insulation gasket and in doing so coolant drains out of the intake...
