I do the maintenance on two cars, a first gen Toyota Tundra (V6 5VZ-FE) and a second gen Nissan Rogue with the 2.5 L QR25DE engine. I've really tried to read here and watch a lot of Youtube (LSJ, Car Care Nut) and get recommendations from a trusted friend with a lot of experience, and honestly I feel less certain about my choices than when I started. I'd be interested in some recommendations from people with more experience and smarter than me.
For the Tundra:
I believe in driving beaters and maintaining them well, just from a personal finance perspective.
Goal for both is engine longevity without issues. I never want to look in the past and wish I'd used a better oil to avoid issues. Obviously don't want to flush money down the drain, but ok with a higher cost oil if it means better protection. I'm ok with changing more frequently too. I don't mind doing the work. Kinda zen.
My suspicion is that the Tundra with the 5VZ that's literally from the 1990s will be easy on oil and anything would work. I also don't know the utility of running a boutique oil in it given it's long history of dino oil and little care for it. Maybe it would be of benefit? Or is that benefit mainly when done from the beginning? And judging from the body scrapes, it's been driven hard offroad in its former life. It's multi-port injected.
For the Rogue, probably not as easy on oil. I don't think it burns oil yet. No issues so far. It's GDI though but at least no turbo.
Anyway, just need some more advice. Like what is all this fuss about M1 ESP?? Too many of my thoughts on motor oil I think have been influenced by UOAs from Youtubers that I now understand from reading here, you can't use UOAs to evaluate the quality of an oil. Teardowns are better. (That would certainly be news to Ford Boss Me. He loves PUP based on VOAs and UOAs.) I was even surprised to see LSJ use UOAs to claim that Napa brand is better than AMSOIL OE (or at least as good) in one of his recent videos. Seems like he would know better than that. Happy to answer any other questions too.
For the Tundra:
- 230K miles. I received no maintenance history from the PO. Jiffy Lube sticker in the windshield. I called them and they confirmed once a year dino oil changes with the emissions check as far back as they could see. As far as I can tell, no engine issues except for a valve cover gasket leak that isn't bad enough to fix yet. Does not appear to burn oil from what I can see (accounting for some loss from the valve cover gasket).
- Will be a low mileage vehicle. <7000 miles a year I'd bet. Unfortunately severe driving conditions. Most trips are 2 to 4 miles. The engine gets fully warm for whatever it's worth on my trips to and from work and around town. I try to get it on the highway as much as I can, but it honestly doesn't get above 45 mph for 90% of its driving except when going camping where I do a little offroading too. So pretty severe all around. Winters are cold and snowy. Summers are hot.
- First oil change after I got it was a Valvoline synthetic. Switched it pretty quickly to VRP when I took over the maintenance given the dino oil used and questionable history.
- Manual calls for 5W-30.
- Plan to keep it until I take it to the junkyard for frame rust.
- Better service history. Probably 80% synthetic changes in the past, at least annual. Pretty much on schedule I'd say, without pulling the maintenance folder. But always at the dealer or another lube place. I think the dealer uses M1 on these, but it's had bulk oil for some changes.
- Manual calls for 0W-20.
- No engine or CVT issues. We've been aggressive with the CVT service, and we plan to keep it long term. Low mileage at 70k now.
- Severe driving conditions with slightly more highway time for road trips. But generally, lots of tanks of gas of just 2 - 4 mile trips on surface streets.
- Currently running VRP in it, since it's had dino in the past for a few changes.
