Formulated lubricating oils meeting OW and 5 W low temperature CCS and MRV performance specification and exhibiting a Noack volatility of about 15 wt% or less are prepared from a mixture of base stocks/base oils of similar kinematic viscosity grade range produced by different final wax processing routes and omitting or reducing the amount of viscosity modifiers and pour point depressants.

Medium and low vi lubricating oils - produced from paraffinic materials

The oils, with V.I. 90, contain (A) an aromatic extract from a de-asphalted vacuum distillation residue of a paraffinic crude oil and (B) an opt. dewaxed vacuum distillate fraction of a paraffinic crude oil. (B) is pref. a wax-contg. light or medium heavy machine oil distillate or esp. a wax-contg. spindle oil distillate, which is pref. dewaxed before blending with (A). A pour pt. depressant, consisting of a copolymer of ethylene with a 3-5 C aliphatic monomer contg. C=C bonds, or a 16-22 C alkyl (meth)acrylate polymer, is pref. included. The oils are produced from the same paraffinic raw materials as high V.I. oils, and (A) is a low value by-product from mfr. of such oils. The viscosity and oxidn. props. of the oils are comparable with those of naphthenic medium and low V.I. oils.

Paraffinic shock absorber oils for vehicles - with improved low temp properties and lower volatility

Vibration damper oils, esp. for shock absorbers on vehicles, contg. as base oils, paraffinic fractions of boiling range 310-400 degrees C, which have been dewaxed, extracted and hydrofined, to give viscosity 21-25 c St. at 20 degrees C, pour point below -40 degrees and flash pt. over 140 degrees C, and other usual additives. The oils have improved cold performance, lower volatility and cost compared with usual naphthenic-based oils. Base oil content is pref. 80-99 (90-99) wt.% and additive content 20-1 (10-1) wt.%. To the base oil a spindle oil selective raffinate with viscosity 5.5-7.0 (around 6.3) c St. at 50 degrees C, density 0.840-0.880 (around 0.860) at 15 degrees C, flash pt. (Marcus) of 135-160 degrees (around 150 degrees C) and pour pt. -45 to -55 degrees (around -50 degrees)C, from a naphthene-based oil, may be added to give closer control of viscosity, the mixts. contg. 70-85 wt. % base oil, 25-14 % spindle oil and 5-1% additives.
