Castrol Magnatec, no API donut

just for fun here's the sds for the 5w30 version which castrol calls "full synthetic"

Haha nice.

Maybe I’m full of it then

SDS sheets are not always a good reference to see what an exact composition makeup of a product is. They are only intended to convey what is a material safety risk and I would not put it past them listing a "like" product that has the same characteristics in regard to a safety risk than listing the exact product.

Back when Magnatec was sold in the USA, the thin grades, like 0W-20 was full synthetic, but the thick stuff was semi. Good oil, regardless. My Civic lived off that stuff until it was discontinued here.

Laugh !!!
So both the full synthetic 5W30 and the synthetic technology 10W30 list "hydrotreated heavy parafinnic" with the same CAS number as their main ingredient, in their SDS.

I circle back to what I said earlier, the 10W30 is semi-synthetic (group-II + group-III) while the 5W30 is full synthetic (group-III).
Both Group-II and Group-III are different degrees of hydrogen treatment of crude oil.

Neither are Group-IV (PAO) or Group-V (ester, AN, etc). What some call "real" synthetics.

But, that "Proprietary performance additives" is the stuff (organic polar molecule) that sticks to the metal surface and helps on starting. I sort of think of it as a small amount of Group-V (which includes anything not in the other groups).

Anyway, this was fun, but Magnatec 10W30 (SP & A3/B4) is a very good oil. I have used it before.

I remember few years ago the last time I bought Castrol GTX Magnatec 10W-30 it said "Full Synthetic" on the jug. Pretty sure about that. Used it in our 2005 car. Don't recall what API. It's a 2005 and any oil will do so it was a don't care.

iirc, had a Noack of 6.7 or 7.1 and for the price ($18 or $19 / 5 qt), a very good Noack #.

Castrol self-certifies that it meets API SP spec and I wouldn't hesitate to trust a company like Castrol. They aren't going to pay for the donut in countries that typically don't care about "American" specs though. I am surprised they don't list at least a JASO spec.

100%

If this product was to be sold in the US, I am quite sure it would get the API certification. The last time I said this there were quite a few angry posts to me, but an oil not having a ceritfication does not mean it didnot/cannot/won`t pass the test. It just means it has not passed the test, and most likely because it was never tested. Testing does cost a lot of money, so a manufacturer would only undertake that only if getting that certification would increase their bottom line more than the cost of that testing plus some return in investment ratio they have.

I have seen this exact oil in a couple European countries as well. API is not as big of a thing outside of the USA, so a manufacturer would not really spend the money if they are not going to sell it in the US or a couple western countries. And the reason why they would not sell it can simply because they don`t find a good spot for this oil in their current offerings. Castrol and M1 already has too many variation in the US market I believe, whereas Pennzoil has a much more straightforward offering portfolio.

TL/DR: I would use this oil in my car unless my car calls for a spesific manufacturer testing (MB, Ferrari, Porsche etc.)

Magnatec in the US used to be the king of titanium additives. I was told that other manufacturer did not / could not replicate that due to the difficulty of working with Ti as well as the cost. Perhaps this Magnatec follows the original formula in that regard.

Fuel in south east Asia like Philippines, Indonesia, Malaysia have high Sulphur. Having A3/B4 is beneficial as long as the car consume no oil or has no catalytic converter.
High SAPS is common for higher antiwear but more harsh to catalytic converter. ACEA has C3 and C5, etc. Für mid SAPS. Pennzoil makes better oil for the price in South East Asia, especielly the GTL platinum ultra. Castrol is known the king of group iii, not PAO. GTL oil is just better in terms pf price/performance.

Point out that Amsoil doesn't have DEXOS approval and see what happens
