Gear Oils

I am looking to service the Jimny in the next few weeks... diffs, gearbox and the usual engine with filter.

The last gearbox and diff service i did i bought the oil from a local agricultural stores, who sell Morris Lubricants.

I bought: 75w-90 API GL 1-5 & 80W-90 API GL 5

However i have just searched the web for the 75W-90 and found this:
www.morrislubricantsonline.co.uk/lodexol...thetic-gear-oil.html

This clearly states it covers all API GL ratings between 1 & 5, and it can also replace 80w90 gear oils.

This could prevent a lot of confusion

An email response from the manufacturer

Dear Sir,

Many thanks for your recent enquiry.

GL grades are made as follows: -

GL-1 - Mineral oil only - Obsolete
GL-2 - Mineral oil with added lubricity - rarely used
GL-3 - Mild Anti wear
GL-4 - Sulphur Phosphorus
GL-5 - Sulphur Phosphorus
GL-6 - Sulphur Phosphorous - Obsolete

Products such as Lodexol SS 75W-90 or Lodexol FS 75W-90 contain an intelligent additive system which is highly stabilised and therefore can cover a multitude of specifications rather than limited to full blown GL-5/6. Most GL-4 packages in the market place are lower treat rate GL-5 packages and therefore could still affect yellow metals.

Regards,
