Synthetic oil

Hi everyone,
New to owning a Morris Minor. I recently had my Morris Minor (Molly) serviced and they have use a synthetic oil in the engine. Is this is ok as I was led to believe that a synthetic oil should not be used for engines as old as Molly's? The previous owner used a 20w50 mineral.
Looking forward to hearing from you
Mrs Hardy.

I wouldn't use synthetic myself. 20-50 seems to be spot on for A series engines. Enjoy your car!

a normal 20/50 mineral oil is fine for the moggy , did they put in a synthetic 20/50

Unlikely - normal mineral 20W50 is what you want in there. If they put in 10W40 'synthetic' or even worse 5W30 both are TOO THIN for a Minor engine. Tell them to drain it, and refill with the correct oil - at no expense to you.. And find a different garage that actually knows what they are doing for the future....... Have to wonder if they got the filter change correct ....

Hi everyone.
Not sure what grade has been put in the engine,will check with gararge first thing on Monday.The gararge in question is approx six miles from were I live, will it be safe to drive?
Thanks very much for your input.

I've never seen synthetic 20/50 so I'm afraid it's likely to be the wrong grade.
Maybe you could phone them first to enquire and then drive it back in to them when they can confirm they've got the correct 20/50 mineral oil & filter to put in?

If it is synthetic 20W50 it will be fine - but will have cost you a small fortune - a needless expense. Strictly speaking of course - if they had looked up the original handbook - it tells them to use SAE 30 oil.....so it may be difficult to pin them down to any wrong-doing. It was up to you to tell them what oil you wanted them to use...

Not cheap and not what your garage used I'll wager.

No - but they may have charged that !! The garage rip-off on oil change costs is unbelievable....charging at the 1/2 litre rate is not unknown.....

There are 5w50 synthetics out there (mobil 1), they should be OK but complete overkill, the first number is the cold viscosity the second the warm so it is the same when hot but thinner when cold helping cold start and getting the oil around quicker, Sierra and Escort cosworths used this and the yb engine is only a 1960s pinto with a fancy head.
I ran it in my lotus twin cam for a while, the only problem was it leaked even more than usual especially when the engine was cold.
