    16 Kia Optima eating oil

    You could pour a combination of HPL and Chuck Norris sweat into that engine for 1,000 mile intervals and that thing would still find itself on the floor of a Hyundai dealership with blown out bearings and oil consumption. Just piled up in corners on crates with nowhere to go. This may be the...

    Castrol edge EP - now claims 25K OCI

    I have not seen Castrol Edge Extended Performance (old or new bottle)in any parts store or Walmart in over a year. And I looked for it too.

    Finally, proof for the 5K mile oil change, or something to laugh at/BITOG fodder

    I could not agree more with this, it’s the manufacturer defects that usually destroy engines prematurely, not the oil changes/oil/intervals (within reason). As long as that oil level is full and changed within some sort of reasonable interval you should be fine for a long time. I have four...

    What is the newest oil you've purchased?

    Pennzoil Ultra Platinum just two weeks ago (and 1,000 miles ago). So far so good.

    Pennzoil Platinum Looks Cleaner than M1 after use - explanations?

    For me personally, Amsoil darkens quickly, then stays about the same color throughout the interval. Mobil1 is more linear, not turning dark/darker until 10,000 miles. I’m running Pennzoil Ultra Platinum right now, and after 1,000 miles it does look similar to what Mobil1 usually looks like in my...

    Real life experience with the oil life monitor system.

    I’m still blown away that the lady from Laverne and Shirley designed the OLM…

    Surprising result from HPL use

    That’s usually been my thought process as well.

    Oil as undercoating to slow down rust

    Vaseline? Never thought of that. I wonder how much one would need to cover an entire frame and undercarriage of a vehicle? Apparently Walgreens sells an off brand for $1.50 for 3.5 ounces…less expensive than the $4-$5 bucks for actual name brand Vaseline.

    Oil as undercoating to slow down rust

    I think you’re right, I used it last season (spray cans) and I believe it was their marine formula…seemed to stay there when I rechecked it in the spring. But I ended up going back to the Fluid Film this past winter - for cost savings mostly as I had some laying around - and yes, there wasn’t as...

    Valvoline Restore and Protect 5w20

    For some reason I’ve gotten to the point where I only tend to care about the starting oxidation point - hoping it’s in the mid 30’s with the thought that it means it has some group lV base stocks in it (PAO) - and if it doesn’t I tend to scroll right on by. I no longer get overly excited about...

    NAPA 5w30 synthetic

    Yeah I used it on and off for a few years in multiple different vehicles, never any sort of issue with it.

    Is the recommended 0-20 bad for engine life?

    I feel the same way, in fact I don’t think many engines could make it to half a million miles without some sort of overhaul or at least have enormous oil consumption/misfires/check engine lights. But the guy documented it pretty well on a Honda forum. He was a medical courier in Texas. I’ve...

    Is the recommended 0-20 bad for engine life?

    There’s a guy on the Honda Accord forums that reached a million miles in his Accord running Mobil1 5W20 for 15,000 mile intervals. A million miles. Having said that, yeah I do prefer 5W30 over a 0W20, and because of that I run 5W30 in my Toyota that recommends 0W20. But I’m not losing sleep over...

    Should I expect nasty black smelly oil?

    Admittedly the first time I owned a GDI engine I did notice the fuel smell and how quickly the oil turned dark in the engine. And I was mostly a highway commuting, eighty miles a day, driver. 2018 Chevy Silverado.

    Unveiling the Superiority of Pennzoil Ultra Platinum Oil: A Detailed Analysis by Mr. Lake Speed Jr.

    Yeah, I think it’s very much luck of the draw with these things. I actually think the harder you run them, and the less it switches into V4 mode, the less problems you tend to have. IMO.

    Updates on Castrol Edge EP?

    Yup, same here where I am (North East). Not a single auto parts store or Walmart carries it anymore. Not a single one within 100 miles of me anyway.

    The truth about oil change intervals and analysis

    Oil is Oil

    I think, like many have said on this thread, under normal driving conditions in most engines a lot of oils will not outperform the other. However taking it to different scenarios…extending drain intervals, severe use, direct injected turbo engines…a higher quality oil will perform better in...

    Castrol Edge HM now claims 15k mi protection.

    Didn't realize that! The last time I looked it was only available in one quart containers.
