Hi There,
I remembered someone on here said Supercheap was selling Castrol Edge cheap

well I went into SCA today and saw Castrol Edge 5 - 30 for just under 30 save 29 something

Anyway a question to those who are using it is it worth the extra $$ on top of Castrol Magnatec (stuff I'm running atm)? at normal prices that is

I'm running 10w-40 atm is it ok to run 5w - 30 in my nb

T'was me!
A lower viscosity is always better in colder climates, so go for it.

It's really a matter of personal opinion as to which is better lubricant.

ahhh, i would go with the mazda recommendations. Lower viscosity, and correct me if im wrong means thinner oil of what's required, which means higher friction between metal. This could mean higher wear on the parts.

I look at my past service reciepts from Mazda and they keep chaning the viscosity, from 10w30 in one servce to 10w40 in another service etc etc.

Wun,
Ask them to stick with the 10w30, it weighs less

5w-30 weighs even less Jake

Castrol Edge 5 - 30 for $29 at Repco this weekend only.

Edge is fully synthetic, so better than semi-synthetic Magnatec

Don't know what NB you have, but Castrol actually recommend 5W-30 with both oils for NB8B (also recommend 0W-40 Edge)

I used Edge 5W30 for years, including a lot of track work. It's fine and it's a helluva lot better than the retail version of Magnatec which is a cheap dyno oil wrapped in heavy marketing. There is a full synthetic Magnatec available to Subaru dealerships called Magnatec Professional - it's alright if you can find it.
