my griff 500 never shows a great deal of oil presure on the gauge

at tick over about 15 psi at about 200rpm just over 30psi it has always been like this
car is checked over and serviced as per the book ive have mentioned this to them but it seems they all do that sir

what do you think

Just got my Griff back from a service (by a different dealer) this morning, oil pressure is now noticeably higher, they insist on Castrol 10/60 rather than the Mobil 1 0/50 or 5/50, they say it's what a V8 needs. Engine also sounds much more 'sophisticated', less little mechanical sounds.....nice bit is, that just emphasises the V8 music more.....can't wait for the drive home!!!!

Angus,
I now live in Amsterdam so I went to the main TVR dealer here called Nimag, they're also the main Morgan dealer. Nice guys, very helpful and certainly seem to know their stuff. When they were changing the headlight bias (to get the Griff registered here) they gave me a go of an Aero 8 they had in for the journalists to review.......very nice but not a Griff.
Anyway, it seems the 'sectret' to a better running (and sounding) big V8 is thicker oil than what seems to be the TVR standard.
BTW, the trip home was magic, meandering road through the woods, top down, sun shining, plenty of V8 music and a big smile!

V8 Developments who replaced my camshaft filled it with Unipart Green 20W50 mineral oil! They say that they have raced engines on the stuff ant it is fine. Certainly seems to have a healthier oil pressure.

Just a thought here. My Griff 500 used to show minus 10 with ignition on( if you know what i mean)but not started. It now reads "zero" at ignition on.

They all do that, Sir.........

.....or at least mine did until a while back (4000 miles) when it's been going loopy during warm up. Have had it checked that it's nothing serious and am watching it and waiting for it to be a consistent failure to try and trace it. Obviously it's somewhere between the guage and the sender - reckon a main dealer would put me to the cost of replacing both only to find it's in the connection in between!!!

My cure for the "less than zero reading" at ignition on cost a matter of pence.

TVR Rover V8s are famous for low oil pressure. It's partly Mobil 1, the most expensive tapwater you can buy. But even after I changed to the Motorsport 15/50 flavour, I can't say I noticed much, if any, difference in pressure. With a warm engine I get 30psi in normal driving, but this can drop to 10 on tickover.

Maybe we need different gauges? If they only went up to 35psi we'd all be happy...

my Griff's been running on Castrol RS 10W/60 all it's life and pressure is 45 at speed and some 35 at tickover

I've been using "expensive water" since I bought the car six months ago and, when hot, indicated oil pressure is only 10 psi (at best) at tickover, and about 30 running. All seems fine, and I'm not inclined to worry unless the oil light comes-on. However, I've been wondering about getting some nice thick oil when the Mobil 1 runs-out.

But - I gather oil consumption is likely to be reduced, and wonder whether this is such a good thing? My oil always looks clean. I've read about people chaging oil between services, but if I'm using a litre of oil every 1,000 miles, in effect, it will have been "changed" twice between 6,000 mile services!

Jim

I have an office in Hilversum and regularly stay in Amsterdam. My Griff never makes it tho... it stays in the UK.

Would be good to make it for a Dutch TVR meeting sometime!

After talking to Ray Webb (V8 Developments) and John Eales (JE Develeopments) the both recommend high viscosity oils for your V8 Rover engine no matter what the state of tune. Either a quality 20/50 mineral oil and change every 3000 or a decent semi/or pure synthetic of 15/50 or higher and change every 6000.
Not the low viscosity Mobil 1

I use Millers Classic Sport a 20/50 semi/synthetic which gives great oil pressure and a quite engine. I have been sprinting and doing track days on the stuff for years. A number of other TVR owners in the North West use the same stuff with no probs. Its about £23 a gallon.

I confirm with Gerjo, the Castrol gives me 45 running and 30 idle and a MUCH quiter engine.....I just hear the nice V8 music now.

Angus, I'll drop you an e-mail on hooking up.
