Don't waste money on 'flush'! I have used the cheap ASDA 20w50 oil for years - no problems at all. Can't vouch for Morrissons - But I suspect it will be just the same oil. Use it! Most important thing is to change the filter - and MAKE SURE the little plate and spring are present under the filter cartridge.

They can be handy but I would avoid a flush unless the engine is relatively new or a new rebuild etc, as it could loosen 30+ years of sludge,carbon buildup in the engine oilways & deposit it on the bearings.
Just get the oil nice and hot before draining so any deposits will be held in suspension in the oil when drained out

oops already bought flush for £5.00 from halfords
how powerful is the flush??

Take it back mate and ask for money back - explain it's not suitable for classic cars!

might just do that.
it needs a decoke anyway, so i might as well do the job properly while in at it. its great having a brother in the trade as you get everything discounted. oil filter for £1.79 and spark plugs for £1.20 each. (keeps me happy)
