Gas in oil

[Oledad]

I have a 2025 with the hurricane 3.0 twin turbo. Got the oil changed the other day and there is a very distinct, very strong Oder of gasoline in the oil. Service manager and one of the techs told me there’s a major issue, one tech has told me 2 times that this is normal. Of smelling gas in an engines oil is normal this is definitely new to me. Anyone else had this issue?

Do you do a lot of short trips ?

Send an oil sample to Blackstone for analysis.

During a cold start the clearance between piston rings and cylinder walls is fairly large until the motor gets to proper operating temperature. This is effectively a gap through which the fuel will get into oil in the crankcase. Direct injected gasoline engines are more susceptible to this sine the fuel does not atomize and evaporate quickly enough when the cylinder is still cold. Also, right after cold start the ECM commands a richer fuel mixture to help the engine run smoothly and heat up quickly. Port injected engines such the hemi do not have this as bad as the fuel has bit more time to evaporate in the port before getting into the combustion chamber. Another thing with the SST hurricane engine is that it’s a turbocharged engine, so the pressure in the combustion chamber is higher, which increases the blow by through the piston rings at cold start up and gets more fuel diluted in the oil.
So, is it normal? Well, it is something that you will have to live with. Make sure to drive your truck long enough so that it can heat up to 200 F and evaporate at least some water and fuel from the oil. Probably a good idea to keep an eye on the egr valve. Most importantly, do not do short trips and make sure to change your oil and filter at 5k miles.

There are charts which outline what is considered normal and different levels above that. I'll attach one I pulled up in a 30 second internet search. It does not differentiate between DI and port injection.

@Oledad , there is no way of knowing how much gas is in the oil without having it analyzed. You don't have a leg to stand on until you do that and have a number to present.
