Not true. High mileage vehicle oils have an additive which 'swells' gaskets, the idea being to reduce/stop seepage.
All you want to know about oil and more... search around for better answers on the high mileage oil, too. A lot to learn here if you like the technical stuff.
As for me, I'm in the same camp with Venom. Whatever syn is on sale will be fine, and you can easily go 7-8k between changes with any of them. I just changed mine with Wally World SuperTech 5W-30 (damn cold here lately). Before that I was using Mobil 1 10W-30 over the summer. The Wally World brand (SuperTech) was, last I heard, being made by Pennzoil. Prior to that it was Valvoline, If you're savvy about the stock numbers on the bottles you can decipher it down to where it was made and by whom.
Filters, avoid the bottom line Fram. There'* just no reason (imo) to get one when you can get a Purolator or Bosch or Mobil 1 or Wix for just a few bucks more. By the way, NAPA Gold and Carquest Blue are both Wix premium filters (excellent filters). Walmart'* SuperTech filters used to be made by Champion Labs, which made some brand name very good filters, but the last I heard that had changed and now the SuperTechs are about like the cheapest Frams (saw some pics of an old supertech and 'new', side by side cut open, huge difference in materials and construction).
Any brand dino oil will be fine if you change it 3-5k depending on driving habits (blends longer and full syns a lot longer), so match it up with what fits your driving habits and budget. Don't skimp on the filter, put the pry bar on the wallet and fork over the extra $5 for a Purolator or Mobil 1 or Wix premium filter.
