The president of mexico would disagree with you. Pemex has a public statement of the areas that will receive ulsd from Pemex. I dont think that pv is one of those areas. Your expetience is o ly pnr vehicle. There are others that will have similar experiences
But I would not try it in a Mercedes powered vehicle or a 500 hp plus motorhome
I would also worry about long term engine problems. How about you buy a 2020 pu and see the results. You can continue using any fuel as youdont have much to lose. A person with a new high dollar vehicle might think differently . Ed Behnke is a long time member and he should not risk damage to his vehicle because one petsontells him it is ok
Gollowing the recomendations of every vehicle mfr
He risks nothing
There is a reason why the engineers have nade thos recommendations
G M will void any guarantees of the emission and fuel systems if they suspect you are using non ulsd No drivability complaints will be warranteed .
A notation is made against your vin and remains with the vehicle.
