Ford NA3.5L V6

[svtrit]

I have a 3.5L NA engine in a 2017 F150. It’s a company vehicle that has to go by a particular maintenance schedule. The engine oil is required to go 7500 miles between changes.

I’ve been driving this truck just over a year and it has 96,000 miles on it. My boss had it before me and it was maintained by the book.

I checked the oil today and found it was 3/4 of a quart low with 5800 miles on the current oil, which was changed at the Ford dealership.

I can’t really find anything on the NA version online about being an oil consuming engine. While 3/4 of a quart isn’t bad, it’s just starting to do it and it makes me wonder. I wish I could try some VRP in it.

Are these oil burning engines?

I added 1/2 a quart of 0w-20 Supertech 10k mile oil from the jug for my daughters Camry that only needs 4.5 quarts and 1/4 quart of drainings from a years worth of various oil changes.

Thanks.

The Cyclone engine series (3.3, 3.5, 3.7) is generally very easy on oil and has great wear characteristics.
In the longitudinal form (RWD) they don't have an internal water pump; makes changes very easy and no internal leaks.
Overall these are great engines; decent power for their size and very robust longevity.

As for the oil consumption, there's always a balance between concerns for rings being sludged up versus the oil itself being a bit volatile (higher NOACK vaporization).

Using the R&P certainly isn't going to hurt by any means. Run a few OCIs of R&P and see if it can address the issue. Nothing wrong with that approach.

I would just monitor it as you move forward and see if it is indeed consuming a little oil. I’ve never seen an issue with the N/A 3.5l consuming oil personally.
I would be more inclined to believe that the dealer “lube tech” didn’t drain it completely and then didn’t fill it correctly. You know how those “Quick Lane” services can be. The key word that I have a problem with is “Quick”.

The longitudinal 3.5 gets nothing but praise, and may be the most reliable of all of them in the f150 lineup. The 6spd behind it also avoids drama. In my 2.7, I found that Penzoil platinum would hold a steady level for 7000 miles, while M1 would drop a quart. Idk why, but after seeing it over three cycles I went back to penzoil.

3.5 NA with 6F55 transmission is a VERY reliable platform. For transverse version you have to watch out for the water pump issues.

The OP's F150 would have a 6R80 transmission.
