Oil Viscosity for the 2.0L i4 - Track Use

[okyou]

How's 0w20 holding up on track? Has anyone experienced oil burning or sent off their oil for analysis after 1 or more events?
Related, has anyone gone up in viscosity, what did you move to and how's it been?

 

[okyou]

Sharing my break-in oil change analysis.
Will follow-up when I have a second one.

When I bought my I-4 a month ago, dealer service said their rep told them to use 0-40 in all cars (not just for track use), and I got a pic of the carton, Valvoline Full Synthetic European Vehicle, 852518. I have been using Motul 0-40 for years in track cars, so this sounded good to me and I am using the Valvoline in the Emira.

that's interesting they said to use it for all cars.

I just watched a Youtube presentation where an exhaustive test was carried out on a Mustang 5.0 litre comparing 5w20 and 5w30 (a slightly thicker viscosity). Ford changed recently to 5w30 from 5w20.
Lab results over 12 months of consistent same pattern driving (daily driver, track each month) showed the higher viscosity to be better overall.
Cold start in cold climates did affect oil pressure, oil being slightly thicker. I was a little surprised by that, since the lowest viscosity of 5 was the same. Once the engine was at working temperature, no problem with oil pressure.

Anyway, the long and short of it is, in warmer temperatures where snow and ice are not experienced, using 5w30 (in Mustangs at least) seems a better choice to preserve engine wear.
Has anyone experienced this in, for example, the i4 AMG?

That will depend if you still have the factory GPF.

I use 0W-30 LiquiMoly...for all your stated reasons. 20 is for fuel efficiency, even in stock form we are running over 30lbs of boost so the added protection is a good idea.

Thanks so much Kaz. With winter day time temperatures where I live (Australia) not going below +5 degrees (C), I had thought of even using 5w30 (Castrol Edge, fully synthetic). However quashed that idea as either way 0w has an advantage for cold engine start up. Is that your thinking too?

yeah it's not below freezing here but it will get very chilly in the winter in the morning...probably could go 5w30 but the shop recommended stick with 0w30
