Switching to Millers oil?

[Buggyjam]

This Millers oil I read of.

Worth using?

987 with 70k miles. Doing an annual oil change and looking at going to go down the route of Millers oil after reading. Plus a former Porsche tech I use mentioned its preferable for high milers to use something other than the Mobil. Which grade would you recommend? It’s currently got 0W40 Mobil one in.

I put Miller's nanotech 10w50 in my 86k mile 996 C4S.

made the switch from Mobil Super3000 to Millers 5W40 NT a couple of years back for the GT3.

Hard for me to say it's empirically superior, but all the evidence I read suggests its a better oil, and the engine feels stronger than ever.

Only negative is it's a little more expensive.

religiously used Millers Nanodrive in my Stage 2 Leon Cupra 420ps for 4 years. Would do the same in my Cayman S but its gotta go to OPC due to Porsche Warranty.

The biggest clue to me is that Hartech recommend it, plus they use 10W-50 Nanodrive (CFS+ now, I think) for all cars on their servicing & warranty plan.

Use it myself and the engine is definitely easier to start and slightly less noisy through the rev-range.

I go with the recommendation of the company that rebuilt the engine in my 997.1, Millers CFS Nanodrive 10/50. I don't know if there's anything more suitable for a non Hartech engine but I can't fault it in mine.

Smashing, thanks folks. Interesting reading. I’ve checked the manual and really can’t see a good reason to stay on the 0W that was in it when I bought it. I know the first number before the W is to do with viscosity when cold (starting and running from cold). The manual say 0W is for “all temp ranges” and 5W has “above minus 25”. Seems 5W40 would be more optimised for the U.K. climate.

Cheers cmoose. Do you still use the millers in your cayman?

I've been using it since my (Hartech) rebuild a few years back.

Aboutto service mine soon and was looking into this further (not as a financial thing) - I've been informed that many companies use the same oil and rebrand it. Apparently Morris Oils are involved with Millers. Don't know for sure though... certainly interesting from a knowledge perspective.

I don't know about the Morris vs Millers thing, though I've just bought some 10W/50 Miller oil having struggled to get the Morris equivalent - it's not cheap, but if it improves the engines reliability, then that's fine (mind is for a tuned Mini, though my 911 will be using from the next service).

You might find this interesting, it’s a bit heavygoing but worth persevering with.

Not sure if Millers features as this is USA based research. I’m going to be using the Amsoil 5w/30 product in my Jensen, and am minded to try It in the Boxster too.

I use Millers Nanodrive 10w50 in my 986. Recommended by Hartech, so far so good after 3 track days!

There's nanoscopic bearing-like particles in the oil that reduce friction - when I used to have my Civic Type R, a few people had seen an increase of 3-5bhp just by changing the oil on those to Millers Nanodrive.

how on earth can you measure that in proper scientific conditions given the large spread in RRs, or even different runs on the same RR?

I changed to Millers Nanodrive 10w-50 in my 76k mile 996.2 3.6, I did notice the warm idle oil pressure rose from under 1 bar to between 1 and 2. Previously I had used 0w-40.

I’d like to know what Hartech think of Rock oil Carbon - another British made oil, which according to their own data at least, appears to be an improvement on a certain ‘nano’ 10w50 oil:

Doesn't read terribly impartially, to me.

Hence wondering why Hartech think of it.

I’ve actually bought some for my aircooled car.

The manufacturer confirmed via email zddp at 1200ish, but as I’ve read about SM/SN oils, zddp is no longer the sole anti wear ingredient
