Introduction:
My 2010 Acura RL(J 3.7L engine) with over 112k miles on it, was using Acura’s 5w-20 synthetic blend oil with Honda’s oil filter for the past 6 years(possibly) by previous owner. Basically looking at the Acura dealer service history, from 2010 to 2014 previous owner paid about $40 for an oil change which to me could indicated a "conventional oil". Then after that in 2014 and up he/she started paying around $70 which would indicate synthetic blend oil formula. Oil changes were done by the Acura dealer for that owner.
My story:
I drive about 5 to 6k miles per 9 months. Almost a month ago, I though why not go with “full synthetic” and I picked up Pennzoil Platinum with the aforementioned viscosity(5w-20) rating. I drove about 500 or so miles since switching oil and to me the engine sounds a bit different with sounds/noises I don’t remember hearing before. This is mostly while engine is cold and not fully warmed up and I am still parked. Nothing out of the ordinary or bad, just different.
Two things to note: the day I went with Pennzoil, I also used a different oil filter which is Purolator One. Before there was a Honda filter. Also the reason I switched, I do short such as 5 mile trips and thought full synthetic would help.
Here are my 3 questions:
1) Could the oil filter OR oil brand OR switching to full synthetic make engine sound different when not at full operating temp?
2) Since this was my first oil switch, would you recommend to do another oil change with same Pennzoil as well, but to go with Honda’s oil filter this time?
3) Go back to that Acura’s synthetic blend as before?
