Servicing the GT4 Options

[3SGTE]

Im planing on servicing the car every 6000 miles, so its now due for an oil change... Fully synthetic oil etc... As im not an experienced gt4 owner,
What else needs changed when i do this??
Does the oil filter need changed etc??

Thanks guys

Well you learn something new every day....
I was under the impression Toyota recommended 5k oil changes for regular engines and 2.5k changes for turbo engines.
But I decided to check to be sure.

For rough conditions [towing, dusty, extensive idling, ect] the interval is 2.5k [3 months] miles for turbo engines [filter is 5k [6 months] miles, so every 2 oil changes] and 3.75k [6 months] for regular engines, with the filter changed every time.

For regular conditions [applies to most of us] the turbo engines are actually 5k [6 months] miles, with filter changes every 10k [12 months] miles.
Regular engines are 7.5k [12 months] miles for oil and filter changes.

And that is on dino [regular, non synthetic] oil.

So, corporate Toyota, that stresses reliability, is comfortable changing oil at some pretty extended intervals.....

Personally, I was changing mine every 3 months, 3k miles with Mobil 1.
But recently [nothing to do with this thread] I've started thinking about getting it tested first.....

In the Marine Corps [and the other services] oil isn't changed on a time or mileage interval, it's sent to be tested, and changed when it's worn out, or too full of contaminates.

That includes the turbine engines in tanks, planes and helicopters.
If you think your turbo engine runs hot, runs hard, or runs in rough conditions, think again. You don't have ****e on those engines.
They do run a very high quality synthetic oil in them though, not regular oil.

Thank you for checking on this. I wouldn't call 5k miles an extended interval though! Remember, BMW and Audi now recommend 15k oil changes for their new cars, even turbo cars (with synthetic though!).

I do about 70% highway driving (20 to 50 mile trips, mostly) and change my oil with Mobil 1 and a new stock filter every 5-7k, which is right in line with manufacturer recommendations.

Often people do oil tests on race motors just to check if there is bearing damage or too much blow-by (metals in the oil or fuel in the oil, etc). Any idea how much the tests cost? I've been curious for a while on my motors...
