Recommended oil for Xflow

[DomRees]

 

What oil should I put into a 1700 Crossflow? (1990 if it makes a difference)

 

I have some Magnatec that I use on the other cars, could I use that or will it bugger something up?

 

Also, the oil that collects in the plastic overflow, best to chuck or reuseable?

 

cheers

Dont re-use the oil that has landed in the breather catch tank.

 

My opinion on oil is that any good semi-synth such as Magnatec is fine just change regularly.

Other opinions will differ

I use Comma Eurolite 10w-40 (http://www.commaoil.com/) because this what Caterham put in it when they serviced it. The engine is a 1700cc Xflow with about 140bhp.

 

I have been told that you should not use a fully synthetic oil in an Xflow

No problem, you can use 15w50 syntetic or not

 

What is bad is syntetic oil like 0w40 or 5w30 which are too thin

Good old fashioned Castrol GTX, cheap as chips (oil), keeps my baby running sweet and quiet, and it says on the label for engines manufactured from the mid '60's too the mid '80's, mine's a 1968 vintage, just right.

Dom,

 

What oil did James Whiting use when he serviced your car 🤔 Check and top up with the same.

 

I'll send you an email shortly.

Personally I use Valvoline Racing Oil 20/50 in my BDR as that is what I was advised by a couple of the Caterham service agents. (Reminds me must get some more.)

 

You'll probably get lots of differing replies to this.

 

But probably a good mineral or semi-synth thickish oil changed regularly should be OK.

These were Silkolene's recommendations which I posted a while back.

 

PRO S 5W-40 for all Septic based engines; this acknowledges the modern Ford appetite for low vis products, maintains very good film strength and oxidation stability, can be expected to perform well with hydraulic tappets. The formulation has been unchanged for many years and was always intended to be a top quality no compromise approach. We have learned fairly recently that the formulation was used by DC as the "high reference" oil for the development of the Mercedes 229.3 specification.

 

PRO S 10W-50 for most modified & standard K series, Ford Crossflows and most others. Rover were keen on 10W/X for the Ks and the comments above apply. A 10W/X would also be suitable for older Fords based on the Crossflow engine. For dry sump engines consider PRO S 5W-40, a lower vis oil will release air faster, don't expect any difficulties provided oil pressure can be maintained.

 

Cheers

Simon

recommanded oil are

15w40 15w50 or 20W50 or 20W60

depend on the climate

20 if hotter or heavy foot

 

I use 15w50 in Motul 300V expensive but very good

as the Mobil 1 same viscosity

 

Good one is the Castrol

 

 

I use previously 10w40 but too thin and so less pressure

at idle at hot

 

If it can help

 

 

Syntetic or not are not a problem

Just syntetic is less sensible to petrol when you use twin webers (flooding)

Otherwise when people says don't use syntetic in a crowflow

they think thin oil as 0w50 or 5w40 ....
