Checking the oil (video)
Discussion
Whilst I'm on a bit of a roll, thought I'd show how to check the oil...
I suspect that the majority of owners do this on a regular basis
And that being the case this is aimed at those who are new to V8V ownership and may be a little unsure of the procedure

FFS Andy....have you swallowed Maverick or something??
I'm here to help fellow V8 owners....... I don't much care what the cruise liner owners get up to
I enjoyed your film Lunablack.
Two points.
1. Our engines do sound 'tappety'.
2. You said, on the initial dip, "If no oil ... need to top-up."
When new to ownership, I was caught out by this. If the car is left for a while, possibly two or three weeks, the oil drains down from the (what is it called) where the dip stick is. Therefore, topping up under those circumstances will over fill.
I think under such circumstances, perhaps it is wise to do the oil check before a car is left for any lengthy period. Then you can do the throttle down start and be sure the oil level is OK.
I am not an engineer, so correct me if necessary.

Nice one Andy.....many thanks, just one question though, the manual says check the level with a cold engine, what difference ( in real terms) will there be if checked with a warm engine???
I'm not really sure, as I've never checked it with a warm engine.... After a run say...I've only ever followed the instructions from the manual..
No matter how long I've left the car, I've always had oil on the dipstick when checking from cold, but it does vary a little on the amount.... Sometimes it's near the bottom, sometimes its half way.....today it was 3/4 up, but I suspect that's because I went for a run yesterday....
What doesn't vary though, is the level when checked after running for 20 seconds.... My car doesn't seem to use a drop, so it always shows at the top mark on the dipstick...
One more thing...
Most people don't realize that checking a dry sump system (like the v8v) is very different from checking a normal wet sump system like the v12. People are conditioned to always wait to check the oil so that it has had time to drain back into the sump, so checking it after an overnight is perfect. Not so with a dry sump because the longer you wait, the more oil from the tank drains into the engine sump, giving a false reading (too low).
That is the reason the engine must be started and then stopped and then waiting a specified amount of time before making the check, so that the sump can be scavenged and the oil returned to the tank. There are so many stories of owners of dry sump cars overfilling the oil because of using a wet sump oil checking technique for a dry sump system. In fact many garages make the same mistake (ask Corvette Z06 owners...)

Thanks Jon..... But NO, don't top up, just add enough so that it shows on the dipstick...2. You said, on the initial dip, "If no oil ... need to top-up."
Don't forget, these engines take around 10 litres, so in theory, unless there is a major problem, I'd be surprised if the level got so low it'd cause damage...
By the way, the amount of oil required to take the level from the bottom mark to the top one is 2 litres..
Talking of dipsticks, anyone seen George ??

That is exactly what I attempted to do (following several weeks of not starting the engine). After adding more than a litre, there was still no oil showing on the dipstick. At that point, I turned over the engine (using the throttle down procedure), and then started it.With hindsight, because originally the oil must have been at the correct level, it now contained a litre too much oil. I then had to syphon out a litre.
It presumably shows, that a considerable quantity of oil, must gradually drain down from the cylindrical tank.
As these cars are sometimes left for periods, I suppose this 'draining characteristic' might sometimes catch out other new owners.
Is that point worth mentioning in your next film release?
I don't think the handbook makes this clear.
