Car 2008 Honda Civic 4-door, automatic trans, no special options, no modifications, a basic 4-door commuter car.
Location Los Angles, Calif (mild climate no show/ice)
Driving habits car not abused, driven carefully but not like a little old lady at exactly the speed limit in the fast lane, often driven at 70-80 to keep up with the flow of LA traffic and often in stop and go traffic at rush hour where average speeds are under 10 mph for much of the commute.
Ambient temp range 35F-115F Days below 40 less than a month. Days above 100F less than a month. Most temps 55-75 per google
Chevron Techron used in the last tank of fuel before each oil change to help remove fallout from cleaning.
Air filter changed every 3rd oil change (15k miles)
Coolant drained out of bottom of radiator (not flushed) and replaced with factory coolant every 15k miles.
Same with trans fluid, drain and fill not flushed, factory fluid also used.
Just trying to give a good idea of the background for the question.
Correct grade and spec per the owner's manual.
Question. If the oil is changed every 5k miles, not using the OLM and using a Honda oil filter does it make any difference what oil is used if the car is kept 100k miles, commute 10 miles one way to work and back (short commute by LA standards), Monday-Friday and errands and occasional trips on the weekend and have the car services by-the-book at either a dealer or an independent with factory trained techs?
