Thanks, I bought all WIX filters and it turns out the WIX filters are more expensive than Bobcat filters. I purchased Mobil Super Delvac 15/40W as it was on sale. Does anyone use Synthetic Rotella 5w-40? I use it in my Jetta TDI and used to use it in my old Cummins Dodge.I use castrol rx super 15W40 diesel grade, as for filters, get a trusted brand name. I haven't heard bad things about Wix filters.
I think you will be fine, you used a brand name oil, i'd just not trust a cheap and nasty no name branded oil.
