Lexus oil change interval is only 5000 miles?

I have my oil changed every  5000 miles. The service man always reminds me
that the oil looks so good he would wait to 7500 miles. (I have 45,000 miles
on my car)


http://www.boston.com/cars/news/articles/2007/04/01/carmakers_increase_oil_change_intervals/

Allmost all other cars have change intervals of 7500 or 10,000 miles.
Why not Lexus? Why can't Lexus go to 10,000 and specify the good
synthetic oils? Gee ... which Asian nation is it that thinks "Business
Is War"?

Hello
5000 miles between oil changes is too short, specially  on synthetic oil. I
change mine every 9.500 miles, 15.000 kilometers, and the oil comes out
clean. As I see it, Lexus are long lasting engines, probably in the
neighbourhood of half a million kilometers or more, around 350.000 miles,
and the benefits of short frequency oil changes, if any, would be longer
engine life, which you would reap , at normal yearly mileages, twenty years
down the line . It is simply not worth it, unless one intends to pass the
car on to your son or daughter.
A friend of mine owned a Toyota Avensis, a model just below the Camry, a mid
sized sedan. He never changed the oil in his car, he just topped it up
during 50.000 miles of hard driving in Germany. The engine , eventually,
blew itself to pieces. Between my misguided friend and a 5.000 mile interval
there must be a happy medium.
 Anyone  can  give me a piece of advice on  a good set of 235 -45-16 W tires
for my GS 430?
Thanks

Your car warranty or guarantee is voided if you do not change the oil
every 5000 miles! And that can be reallllllly serious if you have the
electronic stuff on your car like the radar packages. You really can
not afford to loose the guarantee and you must have an extended
warranty on the car to drive it over the 50,000 mile (83,333 Km)
guaranty period. It is all too easy to run up repair bills of 10% of
the car purchase price on these little goodies.

You really don't understand the warranty, do you.

Not changing the oil on schedule does not affect the warranty for the
radar components, for example.

Get a clue.

Toyota lowered the oil change interval down to 5000 miles from 7500
miles for a reason. Their engineers aren't as confident of their
sludging designs as you are. Of course your warranty is void going
over 5000 miles.

What gives is that Lexus does not specify synthetic oil. If you use
synthetic you can go at least 7500 miles between oil changes, more if
the miles are highway.

20,000 miles between oil changes? No oil filter that I know can last
that long. Have you seen any oil analysis results that indicate 20,000
miles is OK? I haven't. Most 10,000 mile oil analysis results clearly
show the oil is getting dirty but is OK for continued use. The only
guy I know who has a 300,000 mile engine changes his synthetic oil
every 3000 miles. I change my Mobil 1 5W30 every 7500 miles or so and
my 3.0L V6 is still running fine at 215,000 miles.

YMMV

All those Hondas out there on the road, and you don't know anyone who
owns one?

Hell, with a 3000 mile interval, you can't tell the difference between
dino and pure synthetic.

www.tirerack.com has reviews from people who have bought tires from them -
this is a good place to start your research.

No, ACAR, no Toyota (or Lexus) can go above 5000 miles without an oil
change. Even if  you use synthetic oil. The warranty is technically
void if you don't follow the recommended service schedule.

Mercedes has 20,000 mile intervals. BMW *only* up to 15,000 miles.
Where have you been hiding all these years?

We have a 1999 Lexus LS400 which we rarely drive;  it only has about
28.800 miles (driven mostly about 1 - 2 times per week to nearby grocery
stores).  If we change the oil every 3000 miles,  it's only about once a
year for us.  Is this OK?  Does just sitting in a (un-airconditioned)
garage put wear and tear on a car's engine?  (It doesn't seem to me like
it would.)

The service rep at the local Lexus dealer suggested a 10W-30 synthetic
motor oil.  According to recent comments that I've seen in this group,
synthetic oil seems to be the way to go.  How much better than regular
oil is synthetic oil?  Also,  I thought you were supposed to use
different weights of oil in different seasons,  but the rep said that
where we are (Houston,  Texas),  the temperature differences between the
seasons is not that great,  so a 10W-30 Kendall bulk oil is OK.  The
difference between January and July average temperatures in Houston is
about 32 - 33 degrees Fahrenheit;  is this true?

Also,  there's one tire with low tread.  He said we might need to buy
two tires,  depending on the condition of the spare.  He said that you
should at least have two tires of the same brand on the same axle of the
car.  (We would,  of course,  be rotating the tires when we replaced the
worn tire.)  What difference does this make,  as long as they're all the
same size of tire?  He also said that if the spare tire is the original
one that came with the car,  we should throw it away,  because it's worn
out.  How can this be true if it's never used?  (I do now remember going
to a Discount Tire in 2001;  the spare may have been replaced then.)

We generally get a different service rep every time we go to the Lexus
dealership.  I guess one reason is that we don't want to wait around.
This is the first time we've spoken to this rep.  I get the feeling
that,  with the bad economy (even here in Houston),  even the Lexus
dealer is starting to try to oversell).  Just wanted the group's input
on this.  Any advice would be appreciated.

Sitting in a garage does not put wear and tear on a car's engine, but
driving it only short trips can.  Multiple short trips means that the engine
and emissions components do not get completely warmed up and so condensation
collects in the engine oil and exhaust system.  The condensate sitting in
the oil does not lubricate like the oil does, and the condensate sitting in
the exhaust will corrode the exhaust.   You should take the car for a long
enough ride for the engine to get fully warmed up every month or two.

As far as changing the oil once a year every 3,000 miles, that is OK.



The oil viscosity recommended by the automaker is listed on the top of the
oil filler cap and in your owner's manual, and that is the weight you should
use.  A temperature difference of 30 or 40 degrees Fahrenheit is little
enough that you don't have to worry about different oil viscosity for summer
and winter.  Synthetic oil is probably the way to go for your car because of
the infrequent short trips and becasuse the engine doen't have a chance to
warm up each time.


The rubber in tires degrades over time, even if it is not used.
www.tirerack.com has an article about tire aging.  While there is no
standard for when to take tires out of service in the U.S., the consensus in
Europe and Asia is that unused tires should not be put into service 6 years
after they are made, and tires should be taken out of service after 10
years.  By the way, a lot of people speak highly of tirerack as a place to
purchase tires and get information regarding tires

Tires on the same axle, that is, the front or rear, should be matched in
brand, model, and general condition beause variances from left to right can
make the car handle poorly so you generally have to purchase tires at least
in pairs.  If the spare is original, replace it with one of the tires you
are replacing.
