But if
@PetitFrereArmada will one day run something thinner than 0W16, then please comeback and share results.
I don't plan to run anything thinner thaN 0w16. I just feel I have no problem mixing oil just because I want to. I do have a stash of oil now that each cost me $2 a quart. My 2020 Hybrid calls for 0W20, but the sale oil I bought is a lot of 0W16 and some 10W30.
My next oil change will be; 2 quarts 0W16 Castrol Edge, 1 quart 0W20 Castrol Edge High Mileage and 1 quart 10W30 Castrol Edge.
I bought this car brand new and I doubt mixing these oils would do anything negative to this car or reduce my hypermiling mileage that I get of 55mpg to 65mpg.
I plan to be the only owner of this car and my goal is to have this car last to over 300,000 miles on odometer. I am particularly comparing this 2020 Honda Accord to my 2008 Nissan Maxima that I bought brand new in 2008. My Maxima had the dreaded CVT transmission, but I drove it hard from day one, mixed oils in it any time I had different brands and the car lasted me 12 years and over 268,000 miles on odometer. The CVT went out on a road trip and dealership wanted $4,500 for a new CVT. Instead of fixing it, I sold the car AS IS on craigslist for $1,000. Then I went and bought my brand new 2020 Honda Accord to replace my dead 2008 Maxima.
If my very well cared for Maxima lasted over 268,000 even though I drove it very hard, I am expecting my 2020 Honda Accord to last over 300,000 miles especially as I am driving the Accord way more gentle than I ever drove my Maxima. Since I hypermile often, I basically baby this car way too much. And I barely ever use the brakes on this car. The amount of time I have stepped on the brakes of my 2020 HAH so far is about 1/3 the normal time I stepped on the brakes of my Maxima for the same amount of time. Many people say the brakes on the hybrid easily last over 100,000 miles and may even get to over 150,000 miles. I am hoping since I don't even use my brakes often, I hope they last over 150,000 miles before ever needing to be replaced.
