Fuel dilution is nothing new

[Oliveoil2]

Car manufacturers have made a calculated risk with DI and fuel dilution. I’m a fan of Facebook Mileage Impossible and there are hundreds of DI cars with mega mileage. I have not seen an engine failure due to fuel dilution. And if there are a few….it not like Kia/Hyundai failure. I think, like most of you, Short trip DI engines are going to dilute the oil with fuel. But there are millions of these cars on the road with owners blissfully unaware of this issue who drive their cars following the manufacturers OLM without problems. We here at BITOG are not who the manufacturers are catering to.

Back in the 60's a 100K miles on a car was a pretty decent run. Today it's a walk in the park for most cars. Simply put yea oil got better, so did fuel management with the invention of EFI. Some of us might say DI could have been considered a step backwards in some instances, especially early DI. Flame suit on.

my dads 68 valiant with the slant6 was oil fouling plugs @145 k. Lesser engines much sooner
