my v6 trooper ran better with iridium plugs rather than standard isuzu/gm genuine plugs

More MPG, BHP  :question

[Selseybill]

Its £1ish  each for the GM plugs which on paper last 20k, don't believe all the marketing bull about those other plugs.

Agree with you here the same plugs cost £2-£3 each more from Halfords.The last 2 set from Vx(45k) caused no problem and did what it said on the box

You can look at it that way if you want Tunnie, with most things these days you do get what you pay for, also there are advertising standards a company has to consider if it wants to stay in business, ...I probably won't notice the difference if i put £4.95 for 5ltrs supermarket oil in the car, or Mobil 1, but I might later on down the line!

GM plugs are proven, loads of V6's doing 200k+

I'd rather replace my plugs each year with GM ones, than go for 4 years on the same 'high performance' ones.

At the end of the day its your money.

not sure bout bhp as mine was remapped and had headwork done, but did see some improvement on mpg, ran on thr higher octane fuel aswell

Don't get me wrong there Dave, I wasn't slighting the GM oil, not by any means, I'm sure Vauxhall wouldn't put rubbish in their cars, I'm not even saying I won't use it myself...I agree cheap oil is false economy...it's the life blood of the engine. But all the components have an effect on the engine's condition...including the plugs and fuel, black sludge is caused by cheap oil and cheap fuel, not enough detergents in the fuel, to keep the costs down they reduce the additives, effects the valve seats etc, plugs effect the burn efficiency of the fuel in the head, which also affects the valves, piston crowns & bores.

I Think I saw something about this recently, but to save me trawling through, can someone in the know just veritfy for me the correct filter for my 2.5 V6 please? is it the VOF93?

The oil is black and I don't know when it was last changed, I'm thinking of buying 1/2 dozen filters and cheap oil for a few changes at short intervals, then filling with Shell Helix Plus semi synthetic, what I usually use.
   It's in for the MOT in a couple of weeks and I want everything as tip top as possible for then.

   What are the correct/best spark plugs for this engine? I used iridium plugs in my MK2 MR2, which I sold to buy this Omega.

This could go on for a very,very long time.I blame you,see what you have done but just asking a sensible question. 

[Ken L]

Yeah, itì's my fault, my fault, lol...I was starting to think the same thing.

[Selseybill]

Use the oil and plugs you want but please don't tell anyone which one's.Cooking oil and bangers work just as well

[Ken L]

Mum's the word..

[Selseybill]

Here we go.
How many ltrs does one need in a 2.0,2.5,2.6,30,3.2

[Ken L]

IIRC mine is a gnats over 6 litres...2.5 V6

[Selseybill]

What's better full synthetic or semi ?

[Ken L]

  OK!

[Ken L]

Time for tea me thinks! I think everyone else has goen already
