2014 Silverado 1500 5.3 oil analysis high fuel dilution


Recommended Posts

Just got results back from my 2014 Silverado 1500 5.3 UOA.  ODO is 12,527.  Miles on oil sample 4,308.  OLM at 44%.

 

Truck sees a decent amount of towing (5k lb boats) and then is a DD for the 12 mile trip to work.  Fuel dilution was at 4.5% and I had just towed a boat 80 miles about 300 miles before the oil change.  

 

Oil was Pennzoil Platinum 0W-20 and Purolator Boss filter.  Thoughts on this analysis?
