My fleet consists of a 2021 Tundra w/5.7 3UR-FE and a 2016 4Runner w/4.0 1GR-FE. Due to their service routine, I practice a 5k or 6 month OCI, whichever comes first. The work commute for the Tundra is a 20 mile roundtrip every 3rd day. The 4R experiences a horrible school and daycare drop-off and pick-up that are within in a mile of the house (would be better fit for an EV or plug-in hybrid). However, long road trips are done using either of the two for vacations. We live in Dallas, TX.
I currently run Pennzoil Ultra Platinum 5w30 with Toyota oem filter in each of them, but lately have questioned its reformulations to follow ILSAC trends towards greater efficiency. From reading here, it seems the HTHS of oils is a large component for engine protection and longevity and something that is trending downward in the American oil formulations, so I started to look at the euro counterparts such as Pennz Euro L 5w30. My apprehension there is how cheap it is compared to PUP. I know cost isn't everything, but the saying of you "pay for what you get" enters my mind.
Another apprehension I have is that the new formulations are geared to address engine designs that utilize turbos, GDI, and address their issues of LSPI, fuel-dilution, etc.. Though it's rumored that some late model Toyotas have low ring tension and may contribute to bypass so I don't know (was going to perform the first oil analysis on the Tundra here next month). Outside of that, my car's engines are simple port-injection, naturally aspirated with timing chains and vvt-i. I don't know if there are unforeseen consequences of running oil with additives that address engines of different design when trying grab an oil with a HTHS of around 3.5?
I know people say you can run whatever you want on engines that are "easy on oil," but what would you recommend for these old-school designs when protection, longevity and cleanliness are your highest priorities?
