well 3.5 is way better than most dino/blend/syn OTC 5w30s. I'd much rather use a VW 507 rated 5w30 than say M1 5w30.

Until I know more about them, I am not convinced that ACEA C3 oil are the best choice for engines that were not designed for them. I know that VW says VW 504/507 is backwards compatible, but it may be a less than ideal choice.

yeah, I agree with mori...

"Low SAPS" oils do have lower TBN numbers, but may hold up very good in their proper application => Modern engines requiring these oils. I worry more about their low phosphorus content.

Mori, you have been using M1 T&S and Delo 400 in your Audi, right?

What will you do when our HDEOs turn into 1% sulfated ash CJ-4 oils? Many of the "experts" say CJ-4 will be backward compatible and CI-4+ oils will be discontinued. However, doesn't backward compatible mean that an oil meets the minimum requirements of the previous standard?
Are BITOG members satisfied with minimum quality lubricants?

Extreme-Duty, I used DELO 400 for an ARX rinse. Other than that I've been using Syntec 5W-40 (~100k mi), M1 0W-40 (~5k mi) and for the last couple oil changes M1 5W-40 (~16k mi).

I like oils that have a sulfated ash content of around 1.2%. If CI-4(+) oil becomes unavailable, I'm sure oils that meet ACEA A3 will be available for quite some time.

I don't think that backwards compatibility automatically implies that the newer spec meets only the minimum requirements for older engines, but I'll reserve judgement until there is some evidence (UOA results and reports of problems) one way or the other.

Can you explain further, or point me towards a resource for reading materials on this?

I have a Nissan Titan and from a lot of the UOA's I've seen, it seems to like an A3 rated oil, but there aren't a lot of 5w30 oils like that, and GC is hard to find. I would prefer the thinnest Euro rated oil I can find as the truck does tons of short trips.

Right now I am using Schaeffer 5w30 synblend. We'll see how that goes at my next UOA.

I wish I could give you more information, but it's hard to come by and I've spilled all the beans I had. [Wink] From what I heard, VW 504/507 has a sulphated ash limit of 0.5%. TBN appears to generally be around 5-6, which is pretty low. I can only presume that these formulations work very well with the latest engines that were designed with this type oil in mind, but as I said, I doubt that backwards compatibility implies that these new oils are ideal for other engines.
