Oil pressures

[bababoom]

Can anyone post what the oil pressure should be on a 400 and 450 if different.
From cold and when warm normal driving.
Thanks

These RV8‘s run on quite low pressures, it's oil volume they need.

Haven't driven mine for a few months but if I remeber correctly I get about 60 psi when cold, 15 at warm idle and between 30 and 45 psi warm driving.

I'm sure others will correct me though.

Everyone's will be different as the senders vary in accuracy.

The only way to check properly is to connect a mechanical gauge.

What you need to look out for is consistency.

Also depends whether pre-serp or not, and as intimated, what grade of oil is used (and what idle speed is set).

Agree with the above comments. Sender more likely to be the issue unless you have a serious oil leak.

Just to set your mind at rest, I have never seen more than 45 psi on my gauge, either with a 4 litre engine in it or with a 5litre, and it generally runs just around 30-35 on the road, sometimes nearer 15 if stuck in traffic in hot weather. The engine change made precisely no difference to the oil pressure readings.

When really hot on a track day (15 mins flat out, water temp at 90, fans running) I can see as low as 15psi on the gauge.
10w60 oil, always full to the top mark, 9.5 litres with a larger baffled sump.

Keep the oil well topped up and as long as it is consistent there probably is not a lot to worry about. Mine uses a litre per 1000 miles BTW

I dont have a car yet but looking at a couple again at the weekend and its something i forgot to ask about.
litre of oil to 1000 miles is that normal?
Seems a lot.

What you have in a Chimaera or Griff is an evolution of a 1950s Buick engine, married to a Ford Musthave gearbox. It will use a little oil. My 4 litre engine hardly used any, my 5 litre uses about a litre per 1000 miles, especially if driven hard. It's not such a bad thing - it keeps everything lubricated.

It's not a 2000s engine - my diesel Audi uses no oil in 20,000 miles.
