Most of the Euro makes are stretching oil changes out to 12K+, albeit on synthetics. Well actually, in Europe, the fuels have MUCH lower sulphur content and they have the ACEA oil rating standard that is MUCH more specific about oil application. |
auto mfgs are recommending insofar as oil change intervals. Buy virtually
any BMW, MB, or Audi in the US and they come with a maintenance reminder
system that tells you when to change the oil. It is a rare car that
recommends an oil change at intervals shorter than 12K miles. I'm not a
believer that these longer intervals are a particularly good idea - I'm just
pointing out that Lexus' 7.5K recommendation is fairly short in this
day/age.

I think the problem is that Toyota now recommends oil changes every 7500 miles, which in my opinion is CRAZY. So you have people that wait till 7500 and then say "Oh I will do it next week" - and that drags onto 10,000 miles. I change my oil every 3k. This is on my ES330 (which hasnt hit 3k yet) and my 4 runner. The "problem" *was* .... the 7,500 mile intervals that NOBODY in the real world qualified for in the first place and then .... exceeded, just like you say! My 2003 4 runner manual still says 7,500. The dealer reminds me that I don't need to come back every 3k miles if I don't want to. I do not remember what my es330 booklet says but that may have a 5k recommendation. |

covering myself because it is apparent there are some people quoting
European practices without a greater of awarness as to WHY the
European markets can run longer oil service intervals with little
concern over sludging. Not that they're immune to sludge ... not by
any stretch.

manual to change the oil every 7500 miles, he will not think about it more
than that. You know a lot about cars, etc. Average Joe goes by what the
dealer says. If you do everything the dealer and Toyota recommend, you
should not be held accountable if you engine develops the sliming issue.
There is enough margin to reach a compromising medium.

intervals and (b) a pity that a dealer would recommend the 7,500 mile
intervals in the light of the gelling hysteria.
Having said all that, I don't really disagree with you about who and
what the new owner will listen to. In my case, my dealer has
winshield stickers and a mailed out reminder program about oil
changes .... at 3,500 miles with the hopes that I'll show up at 5,000
miles.

For Peugeot cars (my last make of car) they went to 20,000 miles for petrol cars, 10,000 for diesels a couple of years ago (with synthetic oil). I'm a bit mystified - why does the USA seem to feel the need for such frequent mile oil changes. My UK spec Lexus IS200 has a 10,000 mile service interval (and no need for synthetic oil). But I understand that the mechanically very similar US IS300 requires 5000 mile services - why?
