20w/50 too thick for a high pressure oil pump?

[danny69]

I have done a pretty thorough search and the consencus seems to be that most people run their OSF on 20/50 oil.

The thing is, my essex V6 sends the oil pressure needle off the top of the scale when it starts up and doesn`t really drop much even when warm and on tick over.

I wonder if I could do with a 10W/40?

What do you reckon?

20/50 is spot on i would say. Thats what i run, and i get around 90psi when cold, dropping to just under 80 when warm all @ 2k

Cheers, I was just a little worried that too much oil pressure could be a bad thing?

But if it works for you I`ll do the same.

[boXXer]

yeah i suppose it can be, but were rediculous amounts i would have thought.

i was recommended to run 20 50

Also you really have no idea how accurate the gauge is if its just the standard Capri OEM oil pressure gauge.

It sounds to me like your pressure relief valve may be stuck. Oil pumps are usually high volume not high pressure. Get it checked with an accurate gauge. Too high an oil pressure can do all sorts of damage to seals and gaskets!

HT's use valvoline racing 20/50 in their engines,if its good enough for a race engine then its good enough for anything

[danny69]

Thanks for all the replies

I will get the Valvoline 20/50 for the next change and if I get the oppurtunity I will check the accuracy of the gauge.

I use Millers 20/50 Classic Sport semi-synthetic in my 3.0 Essex.

 

Guage goes to three quarters up when cold and settles to just over halfway once warm

 

That's with a standard oil pump.

Exactly what Steve @ Vulcans told me to use in mine when he built it. They did a breakdown test on different oils, and Valvoline was miles ahead of the rest.

I had at least 3 cam failures - worn lobes, untill I went to Valvoline 20-50, no problems ever since.

 

All the Valvoline stuff is great, diff & gear oil too.
