    ENGINE OIL VISCOSITY PUZZLE

    The answer is yes. What you're really getting when you pay the premium for a true real full synthetic is manmade oil molecules that are all identical and perfectly sized spheres which guarantees consistent and uniform lubrication performance, versus crappy nature-made dino oil which is made up...

    Marine 454 UOA

    VR1 is available as monogrades - SAE 30 through 60. If you don't need to start in cold weather, they'd be perfect for your application. They won't shear since they don't have VII's.

    Would you buy a new BMW F850 for nearly 16 large knowing that the engine is from China ?

    For their entire lineup, starting with the '21 MY I believe. And the DVD's for previous models that they used to sell, they've stopped selling.

    Would you buy a new BMW F850 for nearly 16 large knowing that the engine is from China ?

    I wouldn't buy any new BMW motorcycle because they now no longer sell service manuals to the public. Service manuals are only available to dealers.

    SV650 photos under valve cover

    It won't look bad unless you've seriously neglected your oil changes. I've got 90K miles on my FZ-09 and it looks as clean under the valve cover now as it did during its first oil change.

    What's the oldest oil filter you've ever used?

    So it was time to do an oil and filter change on my bike. Bought a Fram XG6607 from Amazon, but when I got it I wasn't impressed. Both the anti-drainback gasket and filter element were noticeably off-center, and there was some dirt inside. Amazon gave me a refund. Then I remembered I had a...

    "Be Careful"

    The reason doesn't need to be logical, or rational. We're human - we all think and act emotionally and irrationally at times. Those of us who choose to ride motorcycles and have stuck with it, do so because we enjoy it in spite of the increased danger and risk to life and limb. And that's all...

    Rotella T6 5w40 OK for very short intervals?

    Unless you can show your shifter toe calibration report from an independent third-party certifier, I'm calling BS.

    Whats the least expensive JASO MA spec full synthetic?

    I run VR1 SAE 40 in my bike and I have never seen it drain out noticeably quicker or thinner than a multigrade 40 (I always do hot oil changes). Too late for you now, but if an oil drained out of my bike's sump like you described, I'd be sending it off for a UOA.

    Motorcycle vs Car Oil Filters

    My bike has over 70K miles on 'car' oil filters (mostly Fram Ultras). Last valve adjustment, top end looked brand new under the valve cover. I don't lose sleep over oil filters....

    2013 Triumph Tiger 800, Rotella T4 15W40, 2000 mi

    Try a monograde - they don't shear. I've been running Valvoline VR1 SAE 40 in my bike for years and haven't noticed any degradation in shift quality over the longest OCI I've dared to run. It also has a lot of ZDDP, if you care about that. My UOA here...

    2001 SV650 Won't Start/Turn Over

    Try jumping the starter directly from the battery to see if it spins - take a jumper cable and run it from the + battery post directly to the terminal on the starter. Make sure the bike's in neutral. If it doesn't spin or it's weak, it's either the battery or the starter (which you said you've...

    Mixing Rotella T4 and T6

    Of the many things I spend time thinking about in regards to maintaining and riding motorcycles, startup wear falls exactly nowhere on the list. But that's just me. Put it another way - I'd bet money that most of the wear on still-running high mileage engines is not due to startup wear. It's a...

    Mixing Rotella T4 and T6

    The temperature of the oils in that video was -35C. I'd wonder how many motorcyclists are starting up and riding their bikes at that temperature. Ignore BLS - he's a copy&paste troll who regurgitates the same misinformation over and over again.
