I am not recommending a 7500 oil change interval. All I said is that people
who get sludge do not change their oil at least every 7500 miles or less.

If your 7500 interval is true, then Hondas, GMs, VWs and many others
will be sludging up with 10,000-15,000 mile oil intervals. So have you
heard any dealer-maintained Hondas sludge up? NO! But dealer
maintained Toyotas had sludged up.

No, Toyota/Lexus interval after 2004 *is* 5000 miles. Look up the
latest schedule on toyota.com. You go 5001 miles technically your
warranty is void.

Toyota seems to having engineering problems with the latest engine and
transmission (U series) designs. It seems today's strict emissions
demands are way above what they are capable of. Owners will have
benefits in using synthetics in a Toyota, but Toyotas aren't designed
for extended drain intervals. Only up to 5000 miles or your warranty
is void.

Volvo is a great chassis maker with excellent safety features, their
XC90 being a good example with its stability control. However, they
buy their turbo engines from a US compnay, maybe Continental or
something like that.

True luxury cars -- many European cars now use 15,000 mile type of
intervals. I mentioned BMW high specification LL-01/04 oils. So which
cars got these intervals? Hint. Hint. And the accelerator pedal
controls continuously variable valve lift to accelerate, not the
opening of throttle plates.

Great discussion guys. I think Route101 is long gone. ;) ;) ;)

What I cant figure is how can change intervals have increased over the
years for some cars when my oil, Mobil one looks pretty bad at 5000,
15000 , it just sounds wrong, I mean they dont hold 5 gallons of oil
or have giant truck filters, and they are gasolene motors. I would
never feel safe waiting that long. If some state 15000 thats a car I
would never buy used as you know the seller went at least 15000. I
skipped one filter change once, when I changed it with maybe 8000 on
it it was realy sludged up, to me, 3-5000 is still the way to go no
matter what oil is used, for all cars. After all it still is a
gasolene motor.

What is a dealer maintained Toyota? Is the oil replaced at least every 5000
miles?

Actually, I have been using Mobil 1 Full Synthetic in my 98 V6 since first
oil change and have had no problems (obviously). Engine still runs
perfectly. I don't really understand why in the 21st century people are not
using full synthetic oils.

Probably most Toyota employees are using full synthetics despite what they
recommend to customers (just like Ray O.).

That is only the case if they can reasonably show that damage occurred
because of lack of more frequent oil change. If a problem occurs that has
nothing to do with an oil change, it has no bearing on the warranty.

Ford has owned Volvo (passenger vehicles) since about 2000.

Not intending to change the thread slightly, but just wondering if any
of you here have heard about the intercharger gadget. It is fitted in
the crankcase vent air intake/exhaust area, not sure just exactly
where. Theoretically it's suppose to cool down this air so more
unburnt fuel is consumed and cleans up the oil and emissions.
Incidently, I'm not selling this and no intentions of trying, just
need a rebuttal for my coffee buddies.

I know Asian and European cars have weird shaped gaskets (more semi-
circular than flat). Flat gaskets have worked fine for me. I never had
a filter gasket leak and don't know anyone who did, really.

Now more and more cars use only replacement filter media in a reusable
filter housing (European mostly). These use pretty standard looking o-
rings for seals. This certainly helps reduce shipping weight and also
reduced used filter waste, but the boxes need to be handled with more
care otherwise you crush the filter.

So I always use a synthetic blend media filter, and not the cheaper,
thinner paper filters that filter down to only 20-25 microns.

One you drop off at the dealer, pay an arm and a leg. And they mostly
"inspect" kinda maintenance is what I meant. People actually pay for
coolant changes every year, but I doubt people actually got them.

I agree that synthetics are great, especially if people intend to keep
their cars longer. However, today's dino oils are quite decent and
most engines really aren't very advanced. More frequent oil changes
also help remove contaminants. So dino every 3000 miles should be fine
for these.
