This was my first time running a Warren Distribution blend, resulting in another good, rather uninteresting report. While this engine seems to be pretty easy on oil, it took the 9k OCI like a champ.

This looks to be a pretty uninteresting report -- at least in a good way. I was slightly concerned with the large hills on many of my drives, along with the consistent 90° - 100°F days that occur over the summer. This report makes me feel better about using a 0W-20 given my conditions. I will...

No surprises in this report. I will feel completely comfortable extended the OCI to 8,000mi/1yr now that powertrain warranty has expired (at 60,000mi) and the Pennzoil Platinum 0W20 seems to be playing well with my 4B11. I recently moved from Chicago to Nashville, and filled the engine back up...

Recently changed the oil in my car and have driven about 10 miles on the new oil. After letting the vehicle cool, when I first check the dipstick there appears to some dark specks clinging to the dipstick within the oil. (See pictures) This has happened both times I've checked after the oil...

Pennzoil Platinum appears to be doing well in this engine, as everything looks great for this OCI just as my powertrain warranty is coming to a close. Wear metals in this case are even lower than my previous reports that had fewer miles over a similar six month change interval; presumably...

Assuming no glaring fuel system issues, and being attributed to cold weather / frequent short tripping, how permanent is any fuel dilution that may occur during an OCI? To clarify, is oil capable of "reseting itself" after reaching full operating temperature on a longer drive, to burn off any...

I was looking to do a drain-and-fill on my CVT for my 2015 Mitsubishi Lancer. Castrol's Transmax CVT fluid meets the "MMC DIAQUEEN Fluid J4" spec that is required by the manufacturer and is one of the most affordable options I can find that meets this spec. As with any drain-and-fill procedure...

I've been using Shell fuels almost exclusively for multiple years now because it's Top Tier certified, everywhere in my area, and I use their Fuel Rewards program. I've heard from various sources that using the same brand of gasoline (and presumably the same additives) can cause build-up over...

I was slightly concerned about how my Mobil 1 had thinned out to 6.98 cSt @100c last change even though wear metals looked good, so I decided to run Pennzoil with a similar OCI to give it a fair comparison, as my driving styles for each were virtually the same. The 4B11 looks like it took well...

Keeping engine within the 6 month OCI as required by the warranty which will expire at 60,000 mi; following the end of the warranty, I will be more than willing to extend the OCI in terms of both milage and time. This change was run though a K&N HP-1004 which is what I threw on again for the...
