    '13 Honda Ridgeline, Schaeffer 9000 5W20, 9k miles

    It's been a long time since I did a UOA on this engine. Pickup has 138k miles on it, almost exactly 9k miles on the oil (Schaeffer # 9004, 5W20). I've never seen UOA numbers anywhere near this low from a J35 in one of these pickups, but I also don't recall seeing many (any?) with >135k miles on...

    How does Castrol SAF-XO have such a low Brookfield viscosity?

    I have a very small (motorcycle) final drive that calls for SAF-XO. There isn't actually a spec, but the re-labeled product is still called SAF-XO. The data sheet I can find is here: http://www.benquip.bz/uploads/products/files/SAF_XO_SAF_XJ_B1174_96.pdf and you'll notice that the kinematic...

    Does LC20 disrupt ATF frictional properties?

    I have Mazda’s FZ ATF in mind in particular. They run their ATF hot in the SkyActive cars (I see 205 - 210F bulk temps every day just driving down the freeway, and 215F is not unusual in the summer). Until or unless I can figure an external cooler, I’d like to keep oxidation and deposits under...

    CRC Friction Guard for oil?

    It’s part of the CRC GDI service pack. The Friction Guard for oil bottle says to put it into the crankcase. No early-change instructions. It gets left in, as far as I can tell. Says it helps fight DI deposits. SDS indicates 3 - 5% each of: 2-ethylhexanol ethoxylated amine heterocyclic ether...

    2015 Mazda 6 Auto-RX rinse Castrol EDGE 0W20

    3,174 miles on this Auto-RX rinse oil. 84,604 miles on the car. Not intended as anything but a baseline, as I recently picked this car up used as a commuter. I have a fairly long drive on the highway & freeway, but not usually too much stop-and-go. 75 miles/day in the Sonoran Desert of AZ. New...

    Forgot: Which studies show the connection between wear and UOA results?

    I thought I had a couple things on point, but I don't. Point me to something?

    Honda VTM-4 (rear diff) fluid VOA

    I haven't seen a VOA of this fluid, which is specified by Honda for use in the rear differential on certain of their all-wheel-drive models. The Ridgeline pickup is one example of a vehicle which uses this rear end box. There is an explanation of this diff from the lead engineer on the Ridgeline...

    Honda DW-1 VOA

    There was some discussion in this sub-forum two or three months ago as to whether Honda's DW-1 (_NOT_ the clones, the actual Honda-branded fluid) is formulated with little to no phosphorus. See here. So, I decided to run a VOA on some I bought from my local Honda dealer from whom I buy lots of...

    Brake fluid turned green; why?

    What makes brake fluid turn green, when it starts out light tan to gold? Flushed the factory fluid on one of my vehicles after 2 1/2 years. It was distinctly darker than new, but just brown. Fast-forward 2 1/2 more years to the next flush. The fluid in the master cylinder, all the calipers, and...

    Honda NC700X Red Line 10W30 2 1/2 year OCI

    So, I kinda forgot to change the oil for 2 years and 4 months. I basically quit riding the bike for over a year. Just an _occasional_ jaunt around the block or up to the library, so lots and lots of sitting and Sta-bil. 6,200 miles, Fram TG filter. Previous UOA is here...

    Interesting way to advertise that you exceed dexos

    Check the web chart on the first page: http://www.cenex.com/~/media/cenex/files...ll%20sheet.ashx I’ve certainly seen vague marketing claims about how great an oil is. I don’t recall having seen an oil presented in quite this way, though.

    Used Honda PSF viscosity (only) test

    Only ran viscosity. 14k miles ago, I drained the PSF reservoir (with a MightyVac) and refilled it a total of 3 times, turning the wheels lock to lock in between each drain & fill. Therefore, this fluid has 14k miles on it. I took a sample this week because I wanted to see how much the Honda PSF...

    What makes an ATF cause pump whine?

    I experience pump whine from my A/T when I use a particular ATF, but not when I use another. What about the ATFs would cause pump whine when using one but not the other? The whine is not severe, but I notice it. Both are recommended for this application. I'm NOT asking for suggestions as to...

    Is Schaeffer's 227 chain Lube specialer than Honda

    Wondering whether any of you have used the Schaeffer chain lube on your m/c chain, and what you think of it. I haven't used chain lube in some time because I use an auto-oiler. However, I picked up a new-to-me project bike, so I thought I'd ask. Around here (I can get it locally) the Schaeffer...

    How wide are the error bars on Seq IIIG tests?

    Curious as to the difference one must see in terms of the cam + lifter wear test in particular, and perhaps piston deposit merits, before a difference is statistically significant. I've been searching around the web, but I'm not seeing repeatability nor reproducibility figures. Help?

    Fork oil vs shock fluid? How do they differ?

    I see that shock fluids are generally lower viscosity than fork oils, and that shock fluids often have higher viscosity indices. That's all I know. Are they designed/built particularly differently in terms of how they achieve the radically different viscosity indices? What about in terms of...

    Red Line 10W30 Motorcycle oil particle count

    This is their MA-rated shared-sump fluid. I did a particle count only, on the new-in-the-bottle fluid. I have a UOA in the motorcycle section, too. Particle count there is noticeably cleaner: http://www.bobistheoilguy.com/forums/ubbthreads.php/topics/4107645/Honda_NC700X_Red_Line_10W30 4 mic...

    Honda NC700X Red Line 10W30, ~5,000 miles

    This is Red Line's 10W30 motorcycle (shared sump) oil. It has around 5,000 miles on it, best I can recall/figure. Somehow, I didn't get the miles entered when I changed it. My NCX has 40,000 miles on it now. I bought it new in '12. It's a great bike that returns me great mpg and never breaks...

    Is there a silicate-free PG coolant readily avail?

    I prefer to use PG coolants because of my helpers. They're older now, so I'm not as worried that they'll slip a finger onto their faces before we finish up and get their hands washed, but we also have furry friend(s) to think of. I happen to have a couple Hondas now, though (a pickup and a...
