Engine oil Shell or OEM Honda

I always used Rotella 5w30 gas truck oil designed for “All Mileage” in my 2005 Nissan Frontier with 95k but it’s been discontinued. I really liked this oil as it seemed to be thicker and remained viscous for longer compared to others. My favorite part about it? NO LEAKS!

I would do 10k intervals in my Honda Fit but a majority of my driving in that car was highway. I'd also need to add a quart after 7000 miles because of consumption.

First gen Honda Insight, takes 2.6 quarts

Shell Rotella T6 5w-40 in my 09 e90 335d (m57)

Supposedly should be changed every 13k miles but I do 7500 to hopefully help extend the life of the timing chain.

23 hybrid accord, the dealership recommended 15k miles

6k is ideal.. so yeah 5k-6k. My 23 civic maintenance light came up between 5k-6k and i had like 15 % left on it

I got my 93 Accord up to 333,000 miles changing oil at 7500 miles, using the cheap synthetic blend Walmart crap, and engine failure isn't what killed the car. When I pulled the head at 250,000 miles to do a head gasket, the cylinders still had the cross hatching from the factory hone so I'm gonna say 7500 miles was plenty often enough. Changing oil more often than required is nothing but wasting money and buys you nothing in terms of reliability or longevity.

2013 Accord V6... I change it every 7500 with full synthetic. Anyone changing before 5k is wasting their money.

I used to do it every 3k cuz I was pro overkill, then 5k, now I just do it when the car tells me to. So around 20% oil life

Rotella T6 Full Synthetic 5w-40... Burns a little.
