R33,rb25 Servicing Checklist

[skidbentz33]

G'Day

My R33 is due for a service and I'm trying to compile a checklist of what needs doing.

I have owned the car for 4 years regularly changing oil filters,oil,air cleaner and flushing the radiator,the Rb25det currently has platinum iridium plugs and the motor was rebuilt from scratch about 70,000kms.

I was wondering how essential the following are to change if they haven't been in 4 years.

Diff oil

Gearbox oil

Fuel Filter

Brake fluid

If anyone could help would be greatly appreciated.

I change my fuel filter every year, at the same time I also inspect fuel hose and clamps and replace as necessary. If you don't know how long the other oils have been in there, have they ever been replaced? or how hard the car has been driven???? then you have reason enough to change them.

I think it varies greatly depending on use

I give it a complete/full service when I buy a vehicle if I don't have proof of when what work was done.

If it's been 4yrs I would do all. I do the fuel filter and brake fluid yearly if it needs it or not.

If your tracking your skyline then you would do the brake fluid after a number of track days or when you boil it.

Diff oil and gearbox oil being in sealed/airtight units - not often. Although depends on temp, contaminants like moisture or particles.

Thoughts will vary on these. You could work off the cars servicing manual and/or the manufacturers life expectancy as a general rule.

Personally IMHO, if it's your daily every 5-7yrs depending on the number of KM's you put on it each year.

also depends what oils have been put in the diff n gearbox prior and what you want from it.

If they were just standard oils then id go for full syn's to treat them with as much love as possible and keep them performing as highly as possible for as long as possible. Especially if you have rebuilt the motor.

Iv not met a skyline owner who didn't say that the gearbox and diff felt immensely better after a change and use of a very good fully syn that's tried and tested for these cars.

Cheers guys, I have enough reason to change them as I like to keep good care of my cars.

I'll put a fully synthetic oil in next - any recommendations on what brand syn is the best?

My mate was telling me that Mobil 1 isn't the best for engine oil any more and it's got me thinking, I've been running Mobil 1 for years.

My car isn't track or daily I have a work car and another dato I drive most of the time, I like to keep the kms low on the skizza.

I will be sure to check the fuel line whilst I'm at it.

Really the difference between fully synthetic oils only matters when you are tracking or running some really high power etc etc.

Otherwise mobil 1 is fine if a bit overpriced for what the product appears to be these days and in comparison to the competition.

I use Castrol Edge titanium 10-40. Good oil, often comes up on special at repco etc.

Im using the Castrol fully synthetic gearbox oil and diff oil too. Works really good and certainly improved the feel of both.

mine is 93 GTST with 170k on it and the box still shifts smoothly and the diff locks up well.

I can remember the names of them exactly but look it up in the oils thread n you will sus it.

That would be great mine is a 93 GTST with 140k the diff and gear box are as old as the car. I have heard Castrol are the best but everyone has there own opinion, I know from a bloke at work they use Castrol in his $80,000 VW R

they are strong bits of kit if they are well maintained and not abused.

and yeah, fully syns are only used if you want the highest performance and longevity in a part. otherwise for most OEM they don't bother. Ur mum driving down the shops n to work doesn't need fully syn, it just wont make a difference except in price.

Iv got 320hp atw pumping through it and I use it as often as I can including some track work. So she gets the fully syn

They arent air tight. Both have breathers
