Lubricants and Oils FAQs
Yes, the synthetic base oil used in synthetic and semi-synthetic engine oils are fully compatible with mineral oils (N.B. This is not necessarily true of industrial oils (compressor, gear oils etc) however. Some specialised synthetic oils in these applications are not compatible with mineral oils. Check with the Caltex Technical Solutions service on 1300 364 169 if guidance is required).
A higher viscosity grade may or may not help the oil consumption problem, and will have an effect of the ability of the engine to start under low temperature conditions as well as having a small effect of fuel economy, but it will do no harm to the engine and thus could be worth trying. Caltex Havoline Premium is an SAE 20W-50 grade and is suitable for older engines, so is a good product to try in this situation.
Generally speaking manufacturers recommend against the use of supplemental additives. Manufacturers specify the standards that they need oil to meet to properly protect their equipment and Caltex formulates oils to meet those standards. Adding supplemental additives is therefore not necessary.
Not only is it unnecessary it is also potentially harmful. Lubricating oils contain a carefully balanced blend of additives, and changing the mix by adding more of one can actually be harmful to the effectiveness of others. Using supplemental additives will at best dilute the additives in the oil formulation, and at worst serious upset the careful balance.
The exception is those few cases where the manufacturer stipulates in the owner’s manual a particular supplemental additive to be used in conjunction with the specified lubricant.
