5w20 to 5w30

The reason I even ask about the 5w20 vs. 5w30 oil in our 5.0 is frankly I guess I just don't feal comfortable with 5w20 weight oil in a high performance car. I am a bit old school on oil in that I was always told to go up a grade if you are working a car or truck like towing a camper or if you have a high performance car and plan to drive it hard. Although my thinking may be out dated you don't see many track or race cars running 5w20 weight oil now do you... Frankly I believe the 5w20 oil was to increase the overall fuel economy of a auto manufacture like Ford and I can understand why they do it esp when they prob have no more oil related failures running 5w20 then a thicker oil weight. It would be interesting to see over 100,000 miles if there would be any wear difference between running a 5.0 hard on 5w20 vs 5w30.
My mustang seems to run fine on the 5w20 oil no tick or noise and although I do wind it up now and then I feel it is nothing compared to the testing or beating Ford gave the 5.0 during it's development. On that note I still don't feel comfortable running the 5w20 so I will prob try some quality 5w30 this summer and most likely stick with that.

It is your car. Run what you are comfortable running according to what you have had success with in your car experience. I used to run straight 40 weight in my aircooled Type 1 VW but that was because it was aircooled and needed the extra oil weight to help absorb the heat from the engine. That was a fully built high performance motor. Other guys ran something else with the same engine. I had good experience with it for the climate I was living in so that's what I ran. Do your own research and run what you want. On the net everyone is an expert. It doesn't happen very often on this particular forum but it still happens.

5W20 oil has to do with CAFE regulations here in the US. The very same tight spec engine here in the US that calls for 5W20 weight gets 5W30 weight in Europe. Same car , same exact engine yet different oil weight! Europe doesn't have CAFE regulations!

5W-30 is not going to hurt your engine. The track pak cars that are supposed to run the 5W-50 supposedly have the same exact engine as the non-track pak cars that require 5W-20 so I would assume you could use anything in between and be okay.

I'm doing mobile one 5w30 in my track pack car when it's due for its first oil change. I have no worries and it's super convenient for me, our local Costco carries it and our Bmw and Gmc both call for 5w30.

Then again, why would someone buy a track pac 5.0 and not track race? Of course that's none of my business. Ba ha ha ha. Stir pot

5w20 is less viscous, and will flow more freely through the engine. Some people have developed the tick from using too heavy of a weight for their oil which resulted in poor circulation through the cams.

Not only that but i spoke to several shop foremans at a few dealerships and according to the handbook you should be using 5w20. They strongly advised me to do so based on the coyote engine manual and i have not had any issues. Tick free so far.

Respectfully, that doesn't make sense. If people are using too think of an oil weight how does the 5.0 with track pac get 5W50 weight? Why is the 50 weight not too thick on the same identical engine that calls for 5W20 weight by your logic

The track pac 5.0 and non track pac do have the same engine. No difference and has to do with suspension mods. If one has a track pac 5.0 and not racing then no need for the 5W50 weight because its just used as a non track pac way.

Thicker oil like 50 weight heats up more, thus the cooler. And if I'm not mistaken 50 weight will eventually shear down to a 30 weight.

I am not an engineer nor am I an engine guru, so therefore I am going to use what is recommend. Always subjective but I'll take the odds.
