What oil are you guys using?

[Abe130]

As above, I have just bought a fresh rebuilt FD and I am currently putting 10/40 mineral oil in. Only problem is the oil pressure is really low, Any ideas?

[Abe130]

this has been answered in your other thread mate

Thanks mate will take a look

EDIT: Acually nobady has told me what oil they are using? is the oil I am running ok?

[SmbFD3S]

To answer your question tho, i use Comma XTech 5/30 semi synth and this has been used in it for the last 9 years (59K on original engine)

[Abe130]

Ah magic, Thanks for the help would you reccomend replacing the 10/40 before running in or during to the 5/30.

[SmbFD3S]

Are you in contact with the rebuilders of the engine ?

The oil debate is a big one, and there are a lot of people on here thats will disagree with whatever you put in lol...
 
PLUS, you can;t mix mineral with synthetic, really really bad idea.  Best bet is to get some advice from a tuner or your engine builder to be honest.  I only use this because the car is used to it and i dont want to start changing things.

Difficult to tell what oil it used to use, This is the car:

I now have the engine in all wiring in and fluids, car is now running smooth on 10/40 halfords mineral oil on a fresh rebuilt engine.

Would it be a good idea to keep using this if its what I have started using on the fresh engine?

Oh and I dont know the builder as it was a friend of the previous owner.

I have been using 10w40 mineral oil for 3 years and the previous owner used 10w40 mineral oil since it had been imported about 6 years ago.

[Hayward North]

so to answer your question, Yes 10w40 mineral is ok.
The other question is witch is better, Best not go there haha
The BIG oil debate

[Abe130]

Thats reassuring thanks steve, plus its cheap to keep topping up with my halfords trade card

[Abe130]

Yea I think there is a big oil debate on 90% of online car forums anyway lol

[SmbFD3S]

Jeez, you got that cheap mate, i\'d have bought it if i\'d seen that ad !!! oh well....
 
You should be fine on 10/40 anyway, most peopl use this i think anyway

[Abe130]

Thanks man,

Yea I was very very lucky to be the first person to contact him, The engine was in his garage and the bumper, bonnet and most of the trim was all over the place but now 2 months later she is one and running smooth!

Can\'t wait for the summer!
