Can 3.6L Pentastar have fuel dilution?

Specially in the winter?
Thank you

Never had a problem. They’re port injected NA V6’s, not tiny boosted direct injected 4 bangers prone to LSPI.

A leaky injector can contribute to fuel dilution.

A leaky injector can contribute to fuel dilution.

How to avoid that? By using good fuel or some fuel additive once in awhile?

 

[rijndael]

Replace the bad injector.

You mention the winter specifically … are you doing a lot of idling?

No, not idling but doing three to five mile short trips sometimes

 

[rijndael]

Short tripping can also contribute to it.

Short tripping can also contribute to it.

Is 3 miles considered short trip?

 

[rijndael]

Yep.

Don’t worry about it, it’s not a problem on these engines.
In winter moisture accumulation would be a bigger issue with short trips rather than fuel dilution. Just shorten the OCI, problem solved.

Our 2013 Charger had an oil oxidation event around 3k on Castrol Mag - it smelled to high heavens of gasoline …
Was driven 2 miles to work and 2 miles back - M-F …
Seldom was on the highway - but that became a weekend ritual after the thixotropic oil change … (unplanned - was just checking oil level)
Back to M1 - Ran a couple bottles of Techron as well …
