Synthetic Oil for Euro

[Eurotony]

I have been using Mobil 1 10w-30w fully synthetic oil in the car since new. I'm changing to Castrol formula R 5w-30w from the next service (40k) due to the cost of Mobil 1 (Castrol is $45 for 5 litres, Mobil 1 is $90) Does anyone have any issues with the Castrol product or the Mobil 1 for that matter.

Thanks

No issue save for not being sure it is 100% synthetic.

If you spend $60 you can get the Motul 8100 which is better.

According to the Castrol Website, Formula R 5w-30w is a fully synthetic oil.

Agree with yFin, Motul is a much better oil.

[Eurotony]

What viscosity weight does the Motul come in??

[baboo]

5W40 for the 8100.

The site says that 5W30 is a "synthetic", but the more expensive 0W-40 it says "full synthetic".

[yfin]

I stand corrected - it is full syn. Thought I should email these guys to check as I have read on a few forums that it is not 100% syn.

Thank-you for your email.

All the products in the Castrol Formula R Synthetic range are full synthetic. The 5W-30 is based on a Group iii synthetic (hydrocracked), while the 0w-40 and 10w-60 are based on Group iv (PAO).

Should you require any further information please ring the castrol Technical Helpline on 1300 557 998.

Thanks for that

whats the difference between the groups?

[aaronng]

Synthetics = Oils modified and tailored to possess specific properties. The 2 groups are different in their source. Hydrocracked is produced from the petroleum base, while PAO is produced from petroleum gas (which is lighter and purer than petroleum base)
