Royal Purple HPS 5w-30 2.6k mi

[JeepJKU85]

Second UOA in the books. 21,500 on the motor. Installed magnetic drain plug recently. Really happy the Banks Ram Air is keeping silicon levels low like a cellulose filter.

See if the iron trends down after a couple more oil changes before re sample, but 8.5 PPM per 1k not too shabby. I will get her to the 5 PPM per 1k standard at some point as motor wears in more.

Spoke with Lake to clarify a little more for peace of mind though. Fuel dilution did come up slightly but it's also been winter lately too.

85 run time hours as well .

Not sure why the title did not update but this was on a 2023 Gladiator 3.6 with 21.5k currently on vehicle.

Are you only running HPS 2600 miles or was this just mid change sample?

No I've been using RP since brand new. Switched to HPS at 8k from the API version. I'll likely go closer to a year next time just wanted to ensure fuel dilution, oxidation value and viscosity was still good. I hardly do 5k a year as its my second vehicle.
