Winterization for newer Raptor motors

Not as critical with a low lift cam (cams in a raptor) applications, but I am not a fan of low ZDDP oils with the Dexos1 rated oils.

Mobil 1 is fine I am sure and likely a step up from the indmar semi syn, but if you are going to pick a Mobil 1 5w30, I would pick a non Dexos 1 variant.

I also wouldn’t go crazy with the ZDDP levels as too much is unfriendly to the cats.

The ZDDP I was talking about is in the SAE 50 gear oil. No problem with cats... or dogs for that matter. [emoji38]

My understanding was ZDDP produces too much phosphorus for the catalytic converters to handle.

Agreed. But the SAE 50 oil i am talking is ONLY being used in the trans gears, so it is not an issue.

I just had same problem of finding the synthetic 50 weight trans oil anywhere locally. Best thing I could find online was 1 gallon of Lucas oil product via Amazon.

I follow you, but was simply saying not all Mobil 1 5w30’s are the same.

If I were choosing a Mobil 5w30 for the raptors, I would choose the non dexos1 versions.

Dexos1 M1 has been too low on ZDDP the past several years.

I would like it to be between 850 and 1100 ppm and Dexos1 M1 has been running 600-750ppm.

I wouldn’t go too much higher than 1100ppm ZDDP for concern on the catalytic converters.

EDIT: according to the 2018 product chart, the Dexos1 5w30’s have improved, previous years were much lower.

But as you can see, all M1 5w30’s are not the same.

I run exactly what the manual says, Motocraft 5w30 semi.

I guess I didn't get the same manual because it doesn't list any info for oil's or qty's. I sure do appreciate this forum and all the help.

Go to the Indmar site and look it up. You can also download a boat user manual from the Moomba archives site under support. Between the both of them, all of the info is there.

Quick question. I’ve drained all the low water points... is it necessary to run the antifreeze, or just extra precaution? I live in Colorado, it’s not in a heated garage.

Thanks for the info on this thread... so far it was a 10 min job :)
