Hey guys, I have a 2005 honda crv (150500KM) that I purchased from my father in law. He kept detailed log book for his maintenance. I've noticed there are a few oil changes were the interval is 7000kms, but the time was 2 years in between changes. The brand of oil is mixed, I guess he used whatever was on sale. Some conventional oil, but mostly synthetic oils. Past 6 years he hasn't been driving it, reason why he sold it.
Should I be worried about the 2 year interval? I'm worried if there is sludge or crud in the engine. Is it recommended to run PP (read on here it has detergents) for 4000kms twice? This engine apparently has no issues with oil brands so I would just use whatever is on sale at the time of OC after the PP. (Maybe do a 8000km OC with a FRAM ultra filter)
OR
just do regular 8000km OC?
