Oil Change to VR1

[Phil]

Hi All I finally got round to ordering some VR1 this week so changed the oil today.

Took the Stag round the block to warm things up. took the first picture with the old Halfords Classic in

The second shot is with the VR1 its blurred as the urge to crash wasnt high

Not a lot of difference in pressure, the placebo effect maybe made me think if felt smoother but I'm not sure

We have a trip to Bentley Wildfowl Trust nest weekend to it will get a good run then.

Maybe I expected a bigger difference but it won't do any harm

I didn't find much difference between the two so I will go by the cheapest next time.

the fuel gauge hasnt moved phil !! when i changed out to vr1 on my new stag it was 25 tickover hot and 50 at 3000 now vr1 its 30 and 60 ....so a notable improvement

Thats what I had expected maybe after a few more miles next weekend. As I had only covered about 10miles between photos I thought the fuel guage had moved quite a lot

False economy - your engine needs the ZDDP contained in VR1 or Millers Pistoneeze.

Don't think much has been found wrong with the Halfords Classic 20/50.

If you check the composition of both oils side by side when changing you will find that the Halfords oil would have broken down to a thin watery composition and the VR1 will still be thick as treacle.

Within 3000 miles?

If that is an oil temperature gauge, the oil is colder on the first photo so the pressure will be higher.
I have no idea what the normal working temperature of the engine oil is, but I would have thought 70-80 degrees in a fully warmed up engine, it will be lower than the coolant temp as it circulates in the cooler bottom half of the engine

Yes you are right the first photo was before the engine had fully warmed through the pressure didnt significantly change once it had

[wilf]

Phil - I suspect your gauge is telling porkies, there HAS to be a difference between cold and hot oil pressures.

As long as you buy vr1 when eurocarparts are running a discount (nearly always) it's almost the same price as Halfords oil.

When I changed to vr1 from Duckhams Q it didn't make much difference to the pressure at 2000 revs but it did increase the pressure at idle by 5+psi. I bought enough at discounted prices to last me another couple of years so I will be sticking with vr1 for a while for sure.

Just got an email flyer for -30% online using MIDMONTH30 at checkout, will take the price down to about £22.50 per 5l

I have an oil temperature gauge reading from the oil transfer housing.
It does take time for the oil to heat up, and yes generally it does run below the water temperature.
However give it some balls, for a longish duration, on a motorway typically, and I have seen the oil temperature rise as high as 130 degrees on occasion. On such occasions an oil cooler would be handy.
One good reason why I have always used synthetic oil for the occasion when the oil temperature does rise a lot without an oil cooler, mineral oil would start to break down.

Very interesting.
