SkyActiv Oil Analysis Thread

So why were they able to process yours in 5 days but I haven't heard anything about mine, which I sent in before yours. I hope it wasn't lost.

I would call your is probably lost. I have heard that happening several times...

Got the tracking? If it's usps, sometimes they are slow with delivery.

2019 CX-5 NA. I'm an extended oil change interval enthusiast at least with port injected engines. I'm not certain that extened OCI's is a good idea with direct injection engines, especially old school GDI like SkyActiv that doesn't have port injectors to keep the intake valves clean. Will not go more than 10K on oil changes with this engine. Like the cleaning ability that the R and P has from the engineered base oil and not the additive package(the Valvoline guy, Lake Speed Jr. interviewed said so). Some stories on the web from drivers with oil burning engines from gummed up rings like the GM 5.3's, Honda V6's, etc getting positive results after using R and P. I must say that the STP/Amalie HDEO 5w-40 did very well the last oil change.
