Is Toyota still forcing you to do 5,000km PMS?

[K.I.L.L.]

My take on this...

A car usually would last about 100,000 before all sorts of problems including major ones pop up. For most of us, we probably do roughly 12,000 to 15,000 a year or maybe even 20,000. If this is the case, then these problems would usually happen after the maximum warranty period right now which is 5 years. If I were a manufacturer, as an attraction to buyers, I can say just have it serviced every 10,000 kms. The owner does save in the short run but what happens in the long run to the engine? Well, who knows but it's ok because the first owner would have already sold the car after that period and it's the second owner who gets the problems with the car needing a top overhaul, gasket replacements and the like. The second owner would just think that the first owner never took care of his car properly.

So in my opinion, if you plan on keeping your car for more than 100,000 or 5 years, then it is in your best interest to have it serviced every 5,000. At the end of it, how much is oil and filters against the value of the car? If you plan on unloading it before it reached 100,000, then go for extended OCIs and 10,000 service intervals. However, because Toyota enforces the 5,000 service interval to keep the car under warranty, a lot of its older cars are still on the road and even cars on the secondary market may prove to be more reliable than other makes.

Just my opinion. I'm not a Toyota fanboy and we use cars from various manufacturers. It's funny how fanboy has gotten such a negative connotation in the last decade.

it's 10k or 6 months whichever comes first

I failed to mention that that figure (and presumably like the one from Toyota Phils.) is already a local adaptation. The GLOBAL standard it seems for oil change interval (for Honda, in this case) can be found here:

Maintenance Schedule for Normal and Severe Conditions - Except European, Australia and New Zealand Models

On a side note. A lot of engines are chain driven nowadays and what prolongs the chain and tensioner life (basically to keep it from clattering, especially during cold starts as the mileage and age of the car rises) is a regular oil change.

Our 1993 Sentra B13 has 122,000kms on the odo; we change the oil every 5,000kms, or at least once a year, using regular mineral based oil. To this day the timing chain and tensioners are still the original ones from the factory and start-up clatter is very minimal.

OT: sir vinj, lahat ba ng kotse na de-timing chain is ganyan? babad din sa langis yung chain pagikot? pati yung mga old school saturn chain driven engine ganyan na?

in fact after the warranty period i've done the 10,000 interval on my old corolla. it's like 20yrs old by now and the owner is still happy with it

The 4AFE is different from the 1ZZ and 1ZR engines... this is the deal:

As for my 2003 Altis, Im already using a FS oil (Motul Htech) but I still do change oil every 5k just to prevent possible sludging of the engine. (this is already outside casa)

i remember a few years ago, the altis (and other cars, too? i don't know..) had a reputation for oil sludging if not religiously serviced...

i also vaguely remember that sometime ago, the altis was up there in the fuel frugality listing..

As per my research, a combination of piston rings designed for low sulfur fuel, a lack of piston-cooling and the nature of the Z engines to run hot in traffic causes the sludging. Synthetic helps slow down the breakdown and sludge formation, but it's not a cure. Some US owners report oil consumption of over a liter between intervals.

That's the price you pay for fuel economy.

The new ZR has improved rings and presumably better piston cooling, but Toyota is still sticking to the 5k interval.

For all local manufacturers, you get the 5k interval unless you use synthetic oil. If you want to go 10k, it makes a whole lot of sense to go synthetic, anyway... unless you want to collect engine-sized paperweights.

There is no way for Toyota to know if you are driving in normal or severe conditions.

Agree kaya 5k nalang golden rule nila for pms :D

Hi Niky! Are the 1NZ and 2NZ prone to this too?

[lowslowbenz]

Our Vios is now using LiquiMoly oil. Every 5k pa rin ang PMS.

Not because Toyota is forcing me. It's because I want it that way.

No experience with the Saturns... but i'd assume they all operate on the same principle (the chains).

I do the same. My 1996 AE101 has more or less 180k on the odometer, oil change done religiously every 5000 kms. The car's engine never gave me any problems. I recently sold it and the buyer was able to drive it home to La Union/Baguio!

I followed the 5000 km oil change even after the warranty of my car expired, in return I got myself a car that is reliable and headache free.
