Is it ok to have a change oil without changing the oil filter?
PMS(Change oil interval) for the City is every 10k, which is why I'm currently using semi-synthetic(Honda says they don't have fully synthetic). I'm on 7k since last change oil and I don't like the way the car's engine performs compared to my older car which gets an oil change every 3-5k. Engine's more refined and quieter with new oil and I'd like to keep it at that.
I'm hoping to do have it oil changed alternately between gas station(change oil only) and CASA(following regular PMS).
What I need to know is if I can afford to not change the oil filter. The reason behind it is to not tell Honda that I'm doing this to avoid problems with warranty, as well as to minimize cause(since CASA charges high for the filter) and that the filter's designed to withstand to perform up to 10k.
I also plan to switch to mineral oil in the process.
