Boosted only Oil Weight Poll

[robvas]

5W20 Mobile 1 Whipple
Any other weight causes issues with cam phase as the cam system is dependent on oil viscosity and Whipple tune is based on 5W20 from what I understand.
Change the weight = risk confuse ECU = possibly risk timing or power gets pulled?
I could be wrong but thought newest Whipple tune had some extra logic to try and compensate for errors caused by people changing viscosity?
+1 Whipple
Why run anything other than 5W20?

Good points below +1 all, yes if you are going to run a higher oil temp continuous track use then yes you might need oil that is lower viscosity at the new temperature you are running at. Since the oil cooler is built in and feed by coolant, that would mean running higher coolant temps?

If you go from 200-220 CHT of stock motor to running cooler 170-190 CHT using colder Tstat, might want to check your oil temps. If running 30-40F colder oil and also going to 40W... won't your oil pump need more torque(HP) and your flow will be lower?

Ancient thread, but it comes up in Google searches.

Whipple's own instruction manual for the 2015 Mustang Whipple kit says:

Whipple highly recommends running Ford Motorcraft 5W-50 full synthetic motor oil (PN #XL-5W50-QGT) vs the stock 5W-20. You will need up to 8 quarts for an oil change along with a Motorcraft oil filter #FL-500.

What is your purpose in quoting this nearly decade old thread?
Helping others?
Helping me?

So are you comparing Apr 5, 2016 post to July 12th, 2019 dated instructions?
Lol. Should have time travelled before posting.

This was about the time community was dealing with plenty of opg failures and suspected 5w-50 was not helping. Having worked Tier 1 supplier and having family and coworkers still at Ford, I asked around and I am sure Whipple was working closely with Ford.

Note: I had one of the first mustang Whipple kits and had to modify the F150 based airbox flange to install in an S550 2015 Mustang.

Example search "5w"?

Maybe more recent relevant post:

Note: Since I was running the Whipple on road courses, I had all kinds of problems breaking stuff and cam phaser codes etc. Differentials, cam phasers, oil pump had to be replaced and went 5.2 pump and pan, etc etc. I did eventually run a divorced coolant rad and electric pump drivers side to use the stock water to oil cooler.

Half decade newer thread?

Follow Whipple advice and run whatever they tell you on whatever kit you get. Consider waiting till CHT 195 before WOT and listen for stock OPG failure and shut it down.

As I said, this thread came up in a Google search, so I figured I would update it if anyone else came across it.

Sorry your panties got all bunched up. Don't take it personally.
