    4 qts of this 4 qts of that

    I'm actually about to do the same thing in my 5.3 Silverado. Have 4 quarts of M1 EP and 4 quarts of PUP taking up space on my shelf. Though I won't make a habit of it, I highly doubt any harm will come of it from one OCI.

    Iceland Gas Station Oil

    Spent a summer and a winter in Keflavik. Gotta day summer was much better, though the northern lights were spectacular. Fell victim to the color coding reverse on the gas pumps (green is gasoline and black is diesel). Fortunately caught my mistake after only having put around 4 liters of gas in...

    Castrol Magnatec - Clinging Molecules Questions ?

    Magnetec...now with 200% more molecules!!! Marketing gimmick, pure and simple. As to your questions: 1. Yes, it clings to adamantium and unobtainium better than kryptonite. 2. Yes, they've measured a .0002 increase in moles in the top end. 3. Yes. But not as sludgy as 80's Pennzoil.

    OCD About OCI's

    Anyone posting on a forum regarding motor oil is at least a little OCD (guilty as charged). I for one try to hit the 0% mark on my OLM as close as possible.

    PUP

    Most importantly, how many horsepower did PUP add to your engine? ...‚ Nice deal on the oil though.

    Options for extended OCI on 2014 Mazda5

    Wife’s car is a 2012 Mazda5. Yes it’s a family hauler, but I love driving it. You’re right, it feels like driving a go cart. [censored] her off when I drive it when she’s with me lol.

    16 Silverado 5.3L, A/C Delco 0W-20, 7745 Miles

    Just remembered...it wasn’t a fram ultra this run, it was also an ac delco filter. Still, the insolubles didnt change so I suppose it did the trick.

    16 Silverado 5.3L, A/C Delco 0W-20, 7745 Miles

    Decided to take advantage of a free dealer oil change, and as you can see from my results, am regretting it. This OCI did occur through an abnormally cold winter and spring and it did do a lot of idling. Miles were probably 50/50 city/highway. Filter was new Fram Ultra. OLM was at 1% remaining...

    Just curious. GM oil life monitor.

    Have gone down to 4%, but feel confident going below that and plan to when the warranty is up.

    Dealer oil change: What did they fill with?

    Dealer oil change: What did they fill with?

    Originally Posted By: Tech819 I googled 88864004 and it comes up bulk 0w20. I had gotten that far, but I figured it would specify whether the bulk oil was full or semi. Also reckoned that there would be different part numbers.

    Dealer oil change: What did they fill with?

    Had my 2016 Silverado 5.3L in for service, and decided to let them change my oil as it was free, and I had heard that AC Delco 0w-20 was now a full synthetic where before it was a semi-syn. I was looking at the invoice and was trying to verify the fill was correct, but I can't find specs for the...

    No sign of Dexos?

    My advice...dump it. Without that label, it's no better than Dollar General SA.
