Castrol oil

[SlimChim]

Is the Castrol Part synthetic Magnatec 10W40 currently on offer at Halfrauds any good for my std 4 litre Chimp that does really low miles?

[sparkesp]

Well, its good enough for mine, and it did 4500 miles last year.

its a bit thinner than recommended tbh, but should be ok on a lower mileage engine - keep an eye on hot oil pressure though, if it gets VERY low then you may get serious crank wear.

Its the only oil TVR POWER use in all the TVRs they service, from a S1 to a Saggy..

I used to use 10/60 from castrol

Now on 20/50 vr1

I preferd the 10/60

I ran it in my Chim for 3 1/2 years and it was fine in the heat of Mid summer Europe.

Thanks, ordered 2 x 4 litres

I used to but it in 25L drums from the fuel merchant for around £100 mark

I'm using Halfords 15w40 at the moment but in my opinion it's too thin at the hot end of the scale and I'm losing pressure when the engine gets hot in traffic.

In something as agricultural as the old Rover V8 I'd rather use something like a 20w50 or even 10w60 as has already been mentioned...

I use and reccomend the witham oil 15/50 semi synthetic race oil very very good holds up well at extreme temperatures the reason for it being semi as opposed to fully synthetic is they are able to introduce longer poymers and other aditives which apparently cannot go into fully synthetic.

ah well I'll give it a try...I tend to get good pressures when cold ~60 but when it get hot pressures are ~10 on tick over....it does seem to have decay'd over the year so guess it's the previous oil (unknown) degrading?

Currently on Valvoline VR1 20w50 mineral ,seems ok but im going on to eather Millers 20w60 semi or Penrite 15w60 semi ,both with zinc.

absolutely.

ALL modern off the shelf have reduced zinc for US emmission legislation.

You need a Millers CSS or COR to preserve your cam and big ends.
Other oils are available and are usually listed as RACE, MOTORSPORT or COMPETITION oils (as Millers is).

You can buy a ZDDP addition for off the shelf oils but why bother?
Useful if stuck away from home though, but a small top up while away wont be a problem to the right oil in the sump.

Just preparing a service pack atm...

You know TVR (and Power) used to use Carlube before they got sponsership from other oil manufacturers... And talking to the guy's down there, they said it was good stuff?? .....

[SILICONEKID340HP]

I keep looking at this stuff ..Morris oils ,used the fully synthetic stuff but found to be to thin at 10w50

What about this stuff ,just enquired about the oil spec.
