Question 1

can i use 5w-30 fuel economy longlife oil in a vauxhall vectra 1.8 16v

Accepted Answer

This is a C3  SAPS oil that indicates it a LOW ASH oil and is most suitable for cars with emission controls a especially PARTICULATE filters. It is suitable for both DIESEL and PETROL  but not some earlier models  .   My car  a KIA specifies C2 or C3  but KIA  say that either is perfectly OK.    Some cars may specify a 5-20 rating but there is very little difference between  5-20 and 5-30m  or even 3-40  There is no such thing as a STOP STAR' specific oil.  The   STOP START bit  is merely a marketing ploy.  Bdeing fully synthetics it remains stable over a longer service period  that mineral or semi-synthetic..   Heavy duty commercial  vehicles have been using extended service oils for many years but up to recently they have been expensive.  I'd say that as long as you use a trusted brand with the correct spec you are OK  Go for the spec man!  Just like  your average garage!!  In bulk  Top spec C3 including GM , Volkswagen , BMW spec C3 is no down to £2 50 a litre or thereabouts . Which would you use if you ran a cash conscious oufit? .

Question 4

My Vauxhall viva says on the engine cap 5w20 can I use 5w30 for a 5w20?

Accepted Answer

If this is the modern Viva & still under warranty then use only the recommended oil. The 20 / 30 figure relates to viscosity at higher temperatures. Since modern engines usd the oil for purposes other than lubrication, its important the oil complies with the API/ACEA specified in the car handbook.
Above given in good faith. Cutting corners on engjne oil especially on smaller higher powered & turbo variants is NEVER a good idea
