Oil Change

[grepin]

Due for an oil change on my R33 as I have done many times. I am about to return to my car after 3mnths of no use. I am thinking before I start it could be a good time to drain the oil as it all should be sitting nicely in the bottom of the sump. Or run it to warm it up so it drains easily.

Any theories appreciated.

You could start it, make the oil change quicker, or do it on a hot day. The idea of starting it is to warm the oil up so it flows quicker

Cold oil will drain a fair bit slower, but why not (if you're patient). After doing that I'd remove the spark plugs and squirt a little oil in each cylinder (not too much), wait a few minutes and then crank the engine (still with plugs out) until the oil pressure light goes out. Should have fresh oil over the inside of the heads when you look through the oil fill hole. Then replace the plugs and fire it up.

Mainly because the engine's been sitting for ages it'll have very little oil in the engine itself and you want to minimise the amount of "humungous pain" it goes through

Be prepared for the car to be a little harder to start and it'll blow smoke if you do that though.

Actually a thought in the pro-old oil group is to turn it over on the old oil and then dump it, because any wear particles generated due to lack of oil will go into the old oil, which you're about to dump. That means your new oil will be cleaner.

It's probably the kind of thing that makes less difference than you think it does, you could probably just change the oil start it and drive off and it'd be fine... heh

Grepin,

Don't worry mate, since I am awayalso, I have asked Chris and Simo to keep the motor tickin over with a few runs up to AIR and also the Hillclimb meets.

As a matter of fact the motor was oil surging as Chris was comming over one of the rises and so he topped it up with Valveline High Viscosity stuff......you know, the stuff you use for old Holdens and the like.

Freebaggin.

Freebagin's right, we have put over 10,000kms on the bitch while you were away. No need to drain it mate, as there is nothing left to drain - we have been running it dry for the past week!!!!!! It sounds a bit rough until you get it up to 10,000rpm, then she's fine!!!!!:bahaha:

Freebagin - how is it stateside?

500 was cool!

I have not problems realising that my car can handle anything you guys can dish out. 10,000 kms no oil indicates you guys are still driving like Grandmas. Have you got the Quater mile under an hour yet. Normally I would expect my RE540's may be worn out after 10000k however if my suspicious are correct re your driving abilities I wouldnt be suprised if I cant notice any rubber missing. We will see. Nearly got a HC for $200 was too late. Dissapointing.

If the car was running at normal operating temperatures the last time it was run, then you can drain it cold (it will just take longer than if hot). As long as the engine was hot the last time the oil was up around the top of the engine, all the crap in it will flow freely down into the sump after you switch the engine off. From then it doesn't really matter how long you wait until you drain it.

However, there will still be a few more contaminants in the sump when it's cold, but not usually enough to be an issue. I still prefer to drain it hot for this reason.

If you run the engine for a few seconds when cold and then switch it off, you'll have the most crap possible around the upper regions of the engine so if you're going to start the engine before the drain make sure it's fairly warm before you drain it.
