I always have trouble finding the spec sheet for Shell stuff and that page doesn't seem to contain it
- i noticed that some other brands GF6 specs were higher viscosity than their GF5 version, so i was looking what the Gas Truck GF6 viscosity would be.The whole "High Mileage" is marketing, but yet some substance to it. It is weird that they put "All mileage"on there bottles as basically all oil is just that, "All mileage", including those marketed as "High Mileage". So yes, it is purely marketing. I really can't answer if it has more seal conditioner in it, but if your oil leaks on the driveway, you likely going to buy more go it, no matter what you use.
Garak, answered it correctly. Shell Rotella Gas Truck is a PCMO. It has no ratings or certifications to be a HDEO whatsoever. This oil has the qualification and certification to be used in most gas engine vehicles on the road. But I like to answer your question considering you have really meant, "What's the benefit to use Shell Gas Truck verses other PCMO? Because it has extra or higher levels of anti-wear additives to it vs. other PCMOs.
Just bought some RGT 5w30 at Wally World with an Aug 26 2020 manufacture date and still listed as SN/GF-5.
