I use both as well without any concern whatsoever. If your OLM is anything like mine, it takes forever to wind down to zero.
I'm at the point now where I do 1 oil/filter change a year and the OLM still isn't at zero. I believe I currently have around 8,000 kms+ on my last OC and I am still at 60%.
I use a Fram Tough Guard, TG2, as I like the larger size. All depends on the type of service/abuse you put your Ram through?
