Castrol GTX Magnatec 5W-30, 8400 KM, 2018 Ford Eco Boost

[cdlamb]

Just rolled over 200000 kilometers recently and submitted both transmission & motor oil.
A bit of fuel dilution again in this report, but nothing that seems to be concerning.

I haven't sent a recent Virgin oil in. Noticing phosphorous & zinc are trending higher than previous samples. Not sure if additives have been added in more recent formulations. Boron seems to be depleted as well, or possible formulation change too from original virgin sample?

That said good report. Wear numbers at or below baseline. The boron number is probably just how the oil is formulated, it is not low critical. I see their "new oil" number but that is not necessarily valid unless taken from the current batch at the Castrol factory, or from a sample of what you put in the engine. Boron is not depleted in service. What measures depletion is the TBN, and I don't see that a TBN was done with this report.

The results of the test overall look good. Fuel seems typical around 3% for your engine. Not sure when they start flagging Boron level but I suppose their bringing attention to it. Looks like their is some left for a bit longer mileage duration though.

Boron readings are always a lot lower on UOAs. I always thought that the boron disappeared from the oil, but I looked into this a bit more and according to this article, low boron readings are caused by measurement problems with ICP-type spectrometers. When an oil sample is exposed to humidity for some time, the boron will drop out of solution and it won't be measured properly.

Boron is a sacrificial additive. It may be a combination of the two happening though. I'd imagine that depletion through the service interval would have the bigger impact overall though.

ZDDP is a sacrificial additive as well, in that it needs to break down in order to work, but the vast majority of the phosphorus and zinc usually still remains in the oil after the ZDDP is depleted.

I had thought that the boron might attach itself to deposits and gets filtered, or that it could become volatile enough to boil off. After reading that article, I'm not so sure though.

Magnatech was discontinued a little while back now. I used that stuff in my Civic and liked it fine. It was cheaper than some other synthetics. Good stuff.

I haven't found any supply issues yet. The suppliers at my NAPA retailer didn't seem to think it was discontinued.

Will have to see, I have enough for 1 more oil change, then need to stock up again.

That is an interesting article and don't remember if it was that article or another that mentioned boron dropout was higher in warmer weather and humidity. Used oil left out in the environment must allow rapid breakdown for boron and might contribute to lower readings.

Magnatec is discontinued. Go to the Castrol website and do some research instead of arguing.

Don't think OP is arguing. They just mentioned that they're not seeing limited supply yet like you may have and just referenced what napa stated. If it is then they'll see soon enough id imagine.

Magnatec is still available in Canada via Napa retailler, Tenaquip and some Canadian tire.

I contacted Castrol Canada, as i wasn't seeing any thing about Magnatec being discontinued on their website.

Apparently the Magnatec GTX has only been discontinued in America maybe?

Are you already unable to get it South of the Border?

Might have to make myself an account and list some Canadian product for sale on Ebay.

Magnatec oil is discontinued in the USA. My bad, it does appear that it is still sold in Canada, per the Castrol website.
