Ignore the nay sayers!!

I use Mobil 1 0w/40 in my 2.5 V6 and my 3.2 V6 plus used it in my old 3ltr V6 and my 2ltr Vectra, 1.8 Cavalier and 2ltr Mondeo before that without any issues! At a guess close on 400k in total on 15-180k engines so well used, with no horror stories or premature explosions

It can be bought for FAR FAR less than Opie charge - Costco is £20 and a few pennies plus the VAT for 5 ltrs

I personally have found since using fully synthetic oil i don't get the mayo on the oil cap/ oil neck. It used to be quite bad on the Signum now its changed, not had an issue since.

But what do i know

As a newbie I would like to add a few questions while on the subject.

Why are the best most advertised oils not recommended? Surely they don't spend all that money on marketing just to sell us....baboons pesh?

Castrol and mobil one are the best oils, I don't understand.

Do I need Fully synth?

I would like to try BMW's oil, it's £120 pounds a litre so must be good....?

Why have I got an ice-cream capachino in my filler neck? Is my head gaskit gone, or is it this oil cooler thing I keep hearing about?

Where is the "dip stick".....?

Sorry for the all the q's I am new to all this.

Love to all,

Chris. Kiss

It does not mean its the correct oil or even the ideal oil.....its certainly not the best oil at the best price (even at costco).

It amazes me the way some class as the holy grail almost Mobil 1 0W-40 yet they are totaly unaware that it is also available in 5W-30, 5W-50 and 15W 50 (and the 5W-30 would be much better suited to the Omega)

My Omega has had fully synthetic (vx which is Fuchs oil) since day one.....much cheaper Thumbs Up!

You're pilloried for even thinking of not using Mobile 1 especially if you 'only' use Vauxhall's fully synthetic in your Smart.

Apr 2011 at 18:02 even the best quality oil looses its properties within 2.5-3k miles.. so no need to invest expensive oil.. standard 10-40 semi synthetic(vx/gm) and frequent changes like 5K miles(some prefer 3500 miles) (less for turbo diesels as its more critical for them) is appropriate

I also posed the question if there is a suspicion oil being burnt or engine worn. my thoughts were and hence decision was for the best way to protect engine (2.0l r reg). Does this change decision relating best oil to use from here on/what is the best one

thinner oils are designed for specific engines and their clearences..

no one can claim that a semi synthetic standard oil has same quality like expensive mobil 1 (talking about 10-40) but if you use mobil 1 for longer distances its benefits will decrease radically..

so if you want to protect your engine, frequent changes is the best approach..
