2019 Bullitt Part #'s

Doesn't look to be anything unique here. Air-filter is the GT350/GT500 unit and everything else looks to be Mustang GT #'s, as would be expected.

Here's a link to the 2019 Ford Mustang Owners Manual. It has some Bullitt specific stuff in it. Suspect this will not be the final, production version seeing as it is listed as ver-1, but here it is:

Hmm they now say 0w20 for daily use and 0w30 for track use. Didn't they use to recommend a 50 for the track? Seem they only recommend the 50 for the 2.3 now.

Hard to follow these manuals sometimes, but what I read is:

2.3L
Normal = 5w30 - page 299 (top entry) - Synthetic Blend
Track use = 5w50 - page 299 (4th entry) - Full Synthetic
Below -22F = 0w30 - page 302 - Synthetic Blend

5.0L
Normal = 5w20 - page 304 (top entry) - Synthetic Blend
Track use = 5w30 - page 304 (4th entry) - Full Synthetic
Below -22F = 0w20 - page 307 - Synthetic Blend

The turbo will generate more heat so that's the reasoning behind the heavier requirements.

They have made tremendous strides in the quality of oil and it's additives, but I still wonder if the specs are a bit low for fuel economy vs protection.

Anyway, I've got a case of Mobil-1 5w30 Full Synthetic in the garage that I'll use. ;-)

Previous(pre-2018) 5.0 track packs, brembo packs and boss cars called for 50 I believe when at the track.

Yes, the Track Pack 5.0L cars called for 5w50 (as does the GT350) vs non-Track Pack calling for 5w20 just the same as the 2017 5.0L.
