Hello, I've been lurking here for years, finally made a account.
I have a 2020 Ford F350 with a 7.3L gas motor. The truck is used in a application that often has it idling about 5 times as much as driving. Typical day might be 1-1.5hr drive, 13hr idle, 1-1.5hr drive. This varies some however.
My plan is for oil changes at 200hrs and possibly extend to 300 depending on oil analyst.
So far I have changed the factory fill at 65hrs/1000 miles and then again at 327hrs/4000 miles.
I have been using RGT and OEM filters.
In my other gas applications(non truck) I use Kirkland Signature Full Synthetic 5w30. I would like to switch from RGT to Kirkland in my 7.3 if I'm not giving up anything from the RGT. The 7.3 is a port injected pushrod motor, I don't think its oil requirements really justify the cost of RGT($30 CAD for 5.28 quarts) at around 3 times the cost of kirkland($21CAD for 10 quarts). If the RGT will actually help the motor last longer I'm ok with the extra cost as I will keep this truck for 6-9 years which might be ~9k hrs.
Looking at the VOA's (links below) one of the things that stands out is RGT has 160 of molybdenum and Kirkland has 82.
Kirkland has a TBN of 8.0, RGT has a TBN of 6.78+
Would love to hear peoples thoughts on how the Kirkland would work for my application.
