    Through their services, you could well end up extending oil change intervals with scientific proof backing it.
    My dad did that in the late 80s and early 90s with a 1986 Corolla sedan. He ended up getting 340,000 miles of mixed use out of it with oil/filter changes at roughly 12-13k using normal oil. Still ran reliably and without smoking when he sold it with 340k on the clock, but was noticeably less powerful than it was when new.

    We’ve used oil analysis for years. If an engine is going South it will often give advance warning.

    Don’t think so, it was 90’s car we had. As mentioned, make sure the oil level is up. Subaru 2.5’s only have something like 4.5 qt capacity, while the H6’s hold 6 qts or more and come stock with a oil cooler.

    You might try the Castrol High Mileage. If it was only a viscosity effect, they’d be rated differently. It worked for us, cheap experiment. If it’s only a seal enhancer that’s different, don’t know what I’d try: our engine didn’t leak oil.

I also did the obligatory transfer case and differentials on both vehicles this weekend as well, only the 90k mile rear differential showed dirty fluid. Everything else looked new dumping out and I was 15k over on my truck for those services.
    I just did the 10k interval with the 15k mile oil for the first time. It came out better than my last oil change, but not as good as I would like to see. I'm still using the 15k mile oil, but I'll be changing it around 7500 this time I think. I use an ACDelco filter.

    Automotive Engine Oil Filter Study

    Motorcycle Oil Filter Cross Reference

    We try to use Purolater Pure One filters, have to check cross reference to see if they work on bikes.

    in an older vehicle, I would suspect oil that does not get "dark" That darkness, is visual evidence the oil is doing it's job, keeping contaminants in suspension especially soot blowing past rings and valve seals, rather than let it coat your metal parts with sludge

    That was a 45k mile Toyota.
    I do wonder though how much of the "dark" then should the filter remove?

    Re: High mileage oil - worth it or marketing scam?

    Color isn't really a good indication of oil condition. Simply look at a diesel. You can change the oil and a few hundred miles later it's black as can be. That doesn't mean the oil isn't serviceable for thousands and thousands of miles more.

    The oil in my Camry is pretty "dark" right now at 7k. The last time I had it analyzed in the 9k range the comment was that it was that I could extend it a few thousand miles before sampling again.

    Oil analysis performed in a laboratory is the only way.

    Color of oil is not directly indicative of anything other than the engine has been run.

    So would Blackstone's standard test tell you how much life is left in the oil?

    No. A key component to that equation is knowing the TBN.

    Blackstone does indeed test for TBN at the customer's request so, Mark, the answer is "yes".



    Call Blackstone and speak with their tech team. They seem to be fairly passionate about what they do.

    Yes, but not that's not their standard test. It's $10 extra.

    My mistake. I missed the word "standard". Indeed the answer is "no".



    Carry on.

    I think it's weird the transmissions are "non-servicable".
    "non-serviceable"? I'd like to see what magic transmission fluid they are using that never breaks down or gets contaminated. I think what they mean is non-serviceable until the warranty expires.

    Many companies are claiming that you don’t need to change the transition fluid any more. But of course they are smart with the wording “good for the life of the transmission” yeah so when that shit fails it’s the tranny that failed and the fluid lasted a second long as the tranny did right? Lol. F that. Zoom Zoom get it replaced every 70-80k

    Re: High mileage oil - worth it or marketing scam?

    There are sensors to tell you if the fluid level gets the slightest bit low, I'm told. They recommend changing every 100k, so it's not like it isn't a sealed unit that isn't serviceable. You can have it serviced or do it yourself pretty easily. I plan to do mine in the next 20k miles or so. My wife's truck I just do a 3qt dump and fill every oil change. That keeps it looking fresh without having to do a full 12qt flush or whatever it takes.

    I just picked up a low mileage Lexus IS for scooting around vs the truck. I'm going to give it a good once over on fluids. It only has 40k miles but is 10 years old, so I think I want to do fluid changes all around.

    What is the over-under on this thread? Think it dies out in December, or makes it through the winter?

    It will have some legs. No one has even mentioned Rotella yet.

    Welp. There goes the neighborhood.

    I still have the oil from my last change sitting in a bucket in the shop. Maybe I'll send a bit of that in. Not sure how much oil residue was in it from the last oil change though. Wonder how much that'll matter.

    Bought 14 quarts of the Castrol Synthetic motorcycle oil . Had a bunch of discounts but it was still $100 purchase. Had four bikes to change in NH.

    Left Boston 8:30pm. Forgot th3 oil..... Bought Rotella T6 to change the dirt bikes. $20 a gallon at Hooksett WalMart.

    They mean you need special tools to do the job properly. Long gone are the days of simple drain and fill plugs or dipstick tubes.
