Question for you. Own a 2013 Acura TL since new, it’s now my commuter after my wife got a new car. It uses 0w20 and has been exchanged every 5,000 miles. I now only drive 3,000 miles every 6 months in this car and it’ll be 6 months in a few weeks. What would you do? Would you change it at 6 months or run it for another 6 months + 3000 more miles?
2 of my 3 vehicles run similar to that: my 2017 RAM 1500 (with 5.7L Hemi) and 2011 G37. The G is known to be hard on oil, so I change it every 6 months regardless of mileage. The RAM has a history of possible cam/lifter issues (depending on part quality), so Ive resorted to changing that every 6 months regardless of mileage. Both of those vehicles get about 6K miles per year, mostly stop and go and year-round driving.
Our 3rd vehicle, the 2015 Lexus, is what is spec-ed for 0W-20. We put about 9K miles/year on it, mostly highway. That's what I will be moving to 6 month changes as well, that way I can not have to rely on oil lasting that long *and* it lines up with the other changes. Note: we're in CT, so our weather ranges from hot-ish in the summer to below freezing in the winter. I prefer to have fresh oil in place for the extremes.
In your case, CA, Honda engine, etc...Id be more apt to try to run the 6K in a year. Maybe get a sample analyzed right now?
OTOH, even the cheapest synth should be able to handle 3K-4K miles per year, so you could change it out just to be safe. Especially in CA where its nice all year
I hate changing oil in the cold.
Id say even dino oil would work, but 0W-20 dont exist from the dinosaurs. Im not sure Id jump to 5W-20 in the Honda engine, though (though we used to have a 20
03 Acura TL and that spec-ed 5W-20)
