*slap @ Dave

still waiting on response from Anna, if any :P

response is coming... just waiting for dad to pull his finger out and get me the prices :( I have been harassing him every day... usually takes a week with this method to get what I asked :(

oh. and by the way. unless its ripped from a 205 litre drum its not cheap.

at autoban and any other retailer the markup on oil is around 15-20% and trade is the same price. its always on specal and there is no money in selling oil retail.

castrol is the worst. every catologe sale its below cost. so putting it simply unless its in baulk its not cheap. and if it is someones getting ripped off :laugh:

group buy on 20L drums?

would going to a motul wholesaler as a club do anything for us?

Not sure... il get the name of where TAFE (well the teachers ordering it ...lol) and we can take it from there...

On a brighter note, dad assures me he will get the info this afternoon or tomorrow morning. Il post it up on Monday as I am generally never on SAU over the weekends.

So you use the 10w40 Richard? Cardigan boy has convinced me to go to 10w50.

yeah I use the 10W40. I think the 10W50 is a bit overkill. I never really get oil temp above 115C on the track and the oil pressure is always good. the chrono has very high film strength etc so I just never thought about going to a 50. plus the closer the first number is to the second number the better as there are less friction modifiers needed then. so a 40 is 4 times the 10, a 50 is 5 times the 10. i don't think there'd be much in it though.

Cannot find 10W50 on the Motul site, they only have 15W50. So with your theory, 15 into 50 is 3.3333.... Which is the better oil?

well in that 50 is only 3.3 times 15 and 40 is 4 times 10 the 15W50 is 'better', in that it will most likely have less friction modifiers used in it. BUT it's only one aspect of the oil question. best thing is to pick an oil which best suits your car, and usage. :rofl:

This is a great idea!^^

I'm also in for a 20L drum of Chrono 300V if its possible.

I think a group buy on oil would go ballistic - it's not like its a part that people would choose to buy or not, everyone uses oil whether they like it or not! >_<

Sorry I meant 15w50. It's the 300v Competition. I have been thinking about using the Chrono for winter but my car has always run fairly hot so I appreciate the extra thickness at high temp. I probably should use a better quality oil cooler but the one I have works ok and the 15w50 gives me the protection I need.

I do notice quite high oil pressure when cold and am particularly careful when warming up the car because when using a thicker oil like this I think the turbo is more suseptible to damage due to lack of oil flow. I never boost at all before the water is up to temp and would be lucky to hit 0.3bar before the oil temp has risen.

As BB says, horses for courses. I am more regularly at 120-130 degrees towards the end of a session whereas he is more around the 105-115 I'm guessing.

    • Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4
    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
