Not sure if anyone watches this guy but as I'm trying to understand how my car (and cars in general work) and maintain it myself I find these videos very interesting and the guy seems knowledgable and has a nice factual presenting style - all the cars are also my favourite era of mercs W123/124/126/140 and the camera angles mean you can see what he's actually doing.
That said I've seen his three ways to kill your diesel engine and he recommends oil changes every 3,000 miles and to bench test injectors every 60k miles and replace the air filter often/clean housing.
I replace the air filter/clean housing once a year (18k miles) so OK on that count but also do the oil then. Now I know 18k is probably on the high side for oil (i intend to do a 6 month one but I'm always too busy/forget, etc) but does anyone change oil/filter every 3k miles?? That would be every 2 months for me?
Also I've never removed/replaced/checked any injectors in 95k miles of ownership (and unlikely to have been done by PO for a long time before). As it gets exceptional mpg that surprises poeple (50mpg + on long runs) and doesn't smoke (except after very long idles/on cold start) does that mean there's no need to start messing around with injectors (and potentially causing more problems)? Or is this something any older diesel owner does all the time.
Maybe I've been taken in because this guy is selling stuff so it's in his interest to sell this preventative medicine - he also has videos on "regular" valve adjustments, diesel purges, etc. But is this normal? Because on this site which is full of enthusiasts and many with great mechanical skills and knowledge I don't think I've read from anyone (perhaps except Submariner1) proactively taking things to pieces and rebuilding them when there's no actual problems/obvious signs that sometnhing maybe wrong... the only thing people seem to do is follow normal service intervals/items until there's a problem...
