What are the Toyota Celica GT4 ST165 engine and gearbox fluids

165 Engine Fluids


Why do I need to know what fluids to put in my car?

If you put the wrong fluids in then you may well shorten the life of your car and/or cause some engine damage.

Some people recommend something else!

That's up to them. Listed here are the recommended Toyota specifications for your engine. Personally, I think Toyota have more than enough experience and skill with engine design, development and maintenance to say what should be used in their engine. Opinions vary...

What are the recommended fluids?
