    Two quick engine oil questions.

    1) I have heard it said that some of us use a zinc (ZPPD) additive as recent EPA changes have lowered the zinc content limit of off the shelf oils. Which do you use, and which would you avoid?


    2) So called 'German Castrol'. Today I was at the autoparts store picking up a few things and saw a 5.1qt jug of the Eropean Formula Castrol for a good price. Most stores in this area only carry the 1qt bottles, if they even stock it, which at $9-$11 a pop makes changes expensive. I picked up the jug and checked the label to make sure I was looking at German Castrol, but the back did not say 'Made in Germany' as expected.....it said 'Made in Belgium'. Has anyone heard if there was a reformulation or was this just a change in manufacturing facilities?

    I do not use any additives since the chemists at the oil company are already paid to figure formulations out for me.

    For the Belgian Castrol, I'm impressed you found it. I suspect you bought 5W-40. The German stuff is 0W-30. I'd use either one, and in fact I'd even top one off with the other and not give it a second thought. However, I am not under warranty and have no idea of either meets the spec for warranty.

    Either is a very good oil from the data I've seen. I'd prefer the Belgian variety personally as in my area it has a more useful viscosity range but either will be fine almost anywhere generally inhabited in the continental Americas.

    Just a warning, I am assuming the zinc limitations are due to effects on the catalysts in most exhausts. To my understanding, without the catalyst, the more zinc the merrier. Many motorcycle oils follow this mentality.

    Again, no first hand knowledge on that one, just passing along what I've read as a discussion point.

    They had figured it out.. then the API came in and said no, you can't use that much ZDDP. So instead of reformulating their oil to maintain the proper balance of anti-wear additives and detergents, most oil manufacturers simply reduced ZDDP to comply and left everything else as it was. The result is a poor performing engine oil with too much detergents. Just look at T6 UOAs before/after the new regulations.



    I wouldn't say the more zinc the merrier, too much anti-wear additives with too little detergents leaves deposits and sludge build up. The catalyst is also a concern (for some).

    One way to side-step the issue is to look at non-API ratings. For example if an oil is ACEA A3, well it's ACEA A3 regardless of whether the amount of Zn has changed or not.

    I do worry a bit about catcons as I don't want to be replacing mine but I've run "diesel" oils in mine with lots and lots of cat-poison-additives and so far, so good, the cats work fine still. I suspect it has to do with how much (or little) is consumed by the motor and of that, how much and which additives actually make it to the cats.

    Spiros, our 'Thou shouldn't mod' brother, I did not figure you would use any additives

    There are many here that love using Rotella T6, and it is from them that I heard a few years back they were required to drop the ZPPD levels. A few of our heavier modded users now add zinc back in to compensate.

    Note that T6 is a diesel oil, so no cat in those to worry about, and most of our heavier modded bretheren are catless, so what Brandon stated holds true.


    As for the European Castrol, I did not buy any. It was either 5W-30 or 0W-30, don't remember off hand. I did buy Rotella T6 0W-40 though.

    The "diesel" oils I've used are M1 turbodiesel truck and Rotella T6. Both are also rated under the API "car" Sx series (so SL, SM, now SN etc.) so they'd generally be cat-friendly. In fact come to think of it it's hard to find a diesel oil that's not cat-friendly and API Sx series; I beieve Delvac, Delvac1, Chevron are all Sx "car" rated as well.

    I did not know there is a 0W-40 Rotella T6; I've only seen the 5W-40. I use 0W-40 and 5W-40 interchangeably in my car, shopping based on price and availability alone. I'll keep an eye out.
