    Interesting - I've never "mixed" oils. I'll have to look into that more.

    I also didn't know this. That said, I'm old school and always change the oil every 3K anyway. But I didn't realize meth would contaminate the oil differently than gas. Good to know.

    You are in Southeast PA right? Give the guys at Helix a call. They can carbon blast the car and review all your issues for you. Ask for Tim or Eric.

    Helix is just a little far to go since Swedish
    Motors is just across the Susquehanna
    from me in Marietta and they have
    extensive MINI experience and training.
    If I were closer I’d go to Helix.

    Not to disparage Swedish Motors, but IMO Helix is worth the drive.

    I hope you can find out the cause & cure it.

    Thanks all.
    I will think hard about this between now
    and the next time it occurs.

    Used about half Amsoil 5W30 XL (almost A3/B3 with HTHS of 3.3) and half Mobil 1 10W30 High Mileage (slightly more viscous than I want but it's the only A3/B3 rated SN+ oil I know of).
    (Of course now that I've said posted this, I'll probably start getting DTCs again - I scan once or twice a week to check for this).

    I run Motul (below) and have had no issues with knock or anything. Remember I run my car hard and spray 100% Meth so my oil gets contaminated faster then regular stock R53’s and that’s why I change it every 3,000 miles or less.

    Oil, even at the price I pay is cheap insurance for built motors.

    Oil specs here: https://www.motul.com/us/en-US/products/8100-x-clean-5w30--2

    I buy my oil from Amazon, 5L for $42.99, free 1 day shipping since I am a Prime member.
    https://www.amazon.com/gp/product/B01G062AD2/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1

    I only use OEM filters and currently at 110,000 miles. Issue free.

    One was thinner than I wanted per hths
    and the other is a bit thicker at 40C
    than I wanted,so I mixed them instead of
    choosing one or the other. Couldn’t find a
    single SN+ oil that checked all my boxes.
    I’m not inclined to believe that some
    horrible interaction or reaction will
    result from combining them together
    In the same oil pan and engine.

    Your oils will play well together I'm sure.

    I've been using Mobil 1 for many years 30 or so with good results. Plus I can catch it on sale at Wallyworld & with the current Mobil rebate it's $13 for 5 quarts.

    After having DTCs (but no CELs) for superknock about once every 2-4 weeks for most of a year,
    I have had not had any in the last 3 months shortly after changing to SN+ rated oil this spring.

    I'm glad you're not getting knock codes now. Can you help me understand how an oil type can cause or prevent those codes?

    SN+ oils are made with more magnesium and less calcium and other factors(reducing deposits) that lessen the formation of small oil/fuel droplets
    that make their way into the combustion chamber
    and promote LSPI (low speed pre-ignition) in TGDI engines.

    Thanks Cristo. I'll have to look into that oil. Maybe time to change the type of oil my GTI uses.
