Gardner 6LW Engine Oil

[Steve.Sharratt]

Hi,

I am trying to work out which engine oil to use in my gardner 6LW which is due for a change. The orginal API SAE30 CC or CD is now obsolete and I am having a difficult time trying to work out what replaced it. I am working on mineral based and monograde but I don't know much more than that. I have some Comma Transflow FL30 which the manufacturer says 'should' be ok (but not enough for a complete change). Can anyone describe the generic grade of oil I could safely use?

Cheers

Steve

Gardner approved use of 15W-40 lubricants around 1987 whilst under Perkins ownership so you are way behind the curve by still using mono grade lubricant.

Any 15W-40 SHPD oil to API: SL/CH-4 will do the job just fine

About £40.00 for 20L of non branded oil on ebay with free delivery and available at any motor factor for not much more.
My Perkins x 2 need 17 litres each,so a couple of drums give an oil change plus a some spare for emergencies or towards next years change.
Decent generic filters from factor at same time and total cost about £100.00.

Millers do a straight 30 oil for Gardners if you want one.

Morris Lubricants also do a straight 30.

At one time straight grades were far less expensive than multigrade lubricants, however I suspect this is no longer the case.

Why anybody would pay the same price for inferior monograde I have no clue. Multigrade oils are made by blending a low-viscosity oil with special additives called Viscosity Index Improver (VII) VII are additives which improve the temperature/viscosity characteristics of oils.

Oils containing these additives, combine the good starting and friction properties of a thin oil at low temperatures with the good lubricating properties of a more viscous oil at high temperatures.

Never bothered looking but I suspect some of these straight grade lubes may not be intended to diesel engine operation but for old gasoline engines which have no oil filter.

LS1, Cat say straight 30SAE for my 3126's. I use Exol Marine 123 which is about £55 for 25 litres. I believe Cat discount the use of multigrade for the turbo's. Is this your understanding too?

Rafki
Different issue, MUI (mechanical) 3126 Cat motors require SAE0 30 to a specific formulation which used to be pricy, multigrade lubes do not suit them.

Got it. Exol is branded Cat.

Thanks to everyone for your advice. Apologies for the slow response but I have been cruising. It looks like I have a lot of alternatives so I suspect I will be doing an oil change in a few days!
