Best place to start is the maintainance guides, most jobs are listed there in detail, many have pictices to support the job.
As for oil, yes semi synth.
You will quickly find there is allways a mention of the trade club (TC Card) through out the forum. Believe it or not this brings severe savings after joining. An example.
V6 water pump Car spares shop £30 or more. (non genuine)
Dealer retalis at £40 + Vat (Genuine)
Trade (cant remember at mo) say £30 + Vat
Club Price. £22ish + Vat
Current deal on on semi synth
4 x 5 litres
Inc Vat £32.53
Oil Filters £1.22 Plus vat
Both at TC Card prices.
So basically most of us dont look at any other oil and do regullar oil changes with the discounts offered by Vx
TC Card can be obtained for £12
But for £20 you get added benfits from Autobahnstormers (ABS) or VauxhaullOwnersDriversClub (VODC)
Pay/join today you might have your card by Tuesday, both clubs have favourable feedback regards sorting out the TC Cards.
Hope it helps.
