Abstract

The invention relates to universal lubricating oil suitable for a mini-tiller and having good oxidation resistance. The universal lubricating oil comprises base oil and a plurality of additives, and specifically comprises the following components in parts by weight: 89.0-95.0 parts of base oil, 1.0-2.0 parts of high-alkali synthetic calcium sulfonate, 2.0-3.0 parts of an antirust agent, 1.0-2.0 parts of polyisobutene bi-butylene phthalein imine, 1.0-2.0 parts of zinc butyl octyl dithiophosphate, 1.0-1.5 parts of sodium citrate, 0.7-2.5 parts of a complex antioxidant, 3.5-6.5 parts of a compound detergent and 1.8-3.0 parts of an ashless dispersant. According to the lubricating oil, common use of lubricating oils for the whole mini-tiller and different mini-tillers is achieved; and in addition, the lubricating oil also has good abrasive resistance, anti-rust property and oxidation resistance, and meets the requirements of people on the anti-rust property.

Description

technical field [0001] The invention relates to lubricating oil, in particular to a general-purpose lubricating oil suitable for micro tillage machines with good oxidation resistance. Background technique [0002] With the development of agricultural modernization, micro tillage machines have developed rapidly in agricultural production in some areas. Domestic small-scale multi-functional micro-tillers mostly use 2.2-5.88KW diesel engines or gasoline engines as supporting power, adopt independent transmission systems and walking systems, and one main machine can be equipped with various agricultural implements. There are only two categories of lubricating oil for micro tillage machines: internal combustion engine oil and gear oil. The former is used for engines and the latter is used for gearboxes. Nowadays, there are many brands and models of micro tillage machines used in the vast rural areas. According to the different fuels used, micro tillage machines are usually divid...
