Hi, Gents. Being curious about what my engine looks like under the covers, I removed the covers, and my god it's the most complicated engine I've ever seen!!! Anyway, I inspected the air filters, my service as per ASSYST PLUS isn't for another 150 days, but the air filters were really filthy IMO. Do these look as dirty to you as I think they are? I replaced them anyway, and I'm probably imagining a bit more pull at high revs, but either way it can't have done any harm... What do you think? I know the car manufacturers have to be conservative with their service schedules, as busy businessmen won't buy a car that says it needs servicing all the time, but on all previous cars I've had, I've changed the oil at least every 6 months, it seems a long time between engine oil changes... Do any of you do intermittent services in between proper service book services? Or am I being "too caring"? High res versions, because these it'd let me attach are miniscule.
