I need to change the engine oil on two cars
1 - Honda Accord 2000 1.8i 1850ccm 136HP Petrol
2 - Ford Galaxy 2012 2.0 TDCi 1997ccm 115HP Diesel

The Galaxy specifies 5.5 litres of 5W-30, the honda 3.8L of 5w-40.

Can i use 5W-30 them both? Life will be simpler - that way and i can get 15L to change the oil and have some left for top up...
 
I would say no. There is more to oil than just the rating, there is specification too. Ford have a different oil for petrol and diesel vehicles so it is unlikely that the same oil would be suitable for a diesel Galaxy and a petrol Honda.
 
As Neil says no they are different oils for petrol and diesel ,however if cost is a criteria try the oil they sell in the larger Asda stores ,very cheap and does the job
 
I would say no but to be fair my most cars can use a different grade of oil depending on the conditions in country ie hot or cold.
my citroen c3 says 5/40w or 10/40w fully synthetic so if both cars were petrol I would say yes but seeing as one is a mucky old diesel I would say no.

That is just the oil grading. Oils of the same grade can have different specifications. Wrong specification can lead to premature wear and poor cooling.
 
Costco do high spec Castrol at excellent prices. There's also Opie Oils if you want to do it online.

Life was so much simpler when "Duckhams 20/50" went into everything (y)
 
Getting nostalgic, with the current plastic pollution problems, I wonder if we'll be going back to buying oil in tins (with the little pull-out spouts)?

I do. Well, the garage that does my servicing (and gives me a couple of litres [in a repurposed plastic canister] in case I need a top up between changes) does - 40 gallon drums of it!
 
We use bulk oil in our garage, a 5-30 low ash that is suitable for both petrol/diesel engines including those with dpf s, use a quality product that has at least the minimum rating that covers both cars. I’m a member of a car club that has a Castrol development chemist among its members, he recommends a Castrol oil for our cars that has “turbo diesel” on the label, that is there because if it doesn’t say TD on the label then many owners of said cars would not buy it, btw my car is 2 litre petrol with a 9000rpm revlimit btw and has functioned fine for years on this turbo diesel stuff.
Many motor factors will sell oil in 20 litre tubs, or you can buy a product that comes in 4 litre cans and buy 3 and have a bit left over for top ups.
HTH.

The Honda will run on anything, the Ford will likely be a lot more fussy, consult the manual and look for the actual specification, buy some oil to match it and it'll also be good in the Honda.

EDIT: Just looked, apparently Ford Aren't that fussy after all, recommending Castrol Magnatec Professional
A5 5W-30.

How is that not fussy? It is the oil that the engines have been developed and tested to be lubricated with. It is also the same oil that Ford sell through dealers in Ford branded containers.

Because it's rather plain old oil, not some fancy recipe produced to meet one particular specification for a certain series of cars, as is annoyingly common with modern TDI engines.

It still has to meet certain specifications. Ford use different grades and specs for their various diesels.

A garage once put 10-40 instead of 5-30 (or numbers thereabouts) in my MX5 and it immediately cost me ~ 5-7mpg, which when you were only getting 30mpg beforehand is quite a difference.

Got them to change it and it went back to normal.

I agree with you there, maybe it is good but it would be at the bottom of my list to buy, Total Quartz is my fave for the citroen if I can get it cheap.
Would put Castrol in my chainsaw maybe

Is Total not Citroen's affiliated oil company. I would imagine Citroen test and develop their engines on Total oil, just as Ford test and develop using Castrol. The oil used should still conform to the required specifications. If buying Castrol oil for a Ford, it should have the Ford Recommendation clearly marked on the front label, if it doesn't, it isn't the correct spec.
