Oil Labelling - What does it all mean? - Tron
For the engine in my vehicle Vauxhall (Z 16 XE - 52 plate 1.6 16v dual fuelled lpg/petrol) I have been using a Unipart own branded semi synthetic that meets or exceeds:

API SL/CF ACEA A3/B3/B4 VW 500.00 and VW 505.00.

What do all these numbers & letters mean please?

Some of the abbreviations are mentioned in the sticky over in Tech Matters.

Thanks DD - so is it a good all round oil then because as from the link you gave me and in comparison to other brands - it meets, betters or exceeds their specs but at a fraction of the cost?

For 5 litres I pay £11 (inc vat) from Unipart.

I couldn't really comment one way or the other. As long as it meets the specs, then it *should* be ok, but someone else might well be willing to give an opinion?
