Reproduced by Castrol Classic Oils UK, an independent company owned by classic car owners, it satisfies the growing demand for true original lubricants for classic cars that were specified when these vehicles were manufactured. Modern oils do not have the properties required by classic machinery and could cause internal distress, not only to the vehicles but to the owners as well.
Castrol Classic Oils are specially formulated in the style of the original products. Using traditional mineral oil and a low detergent formulation, Castrol Classic Oils are the right choice for your cherished classic or vintage vehicle.
Older engines have very different requirements to modern engines. With larger oil galleries and a greater reliance on splash and cling properties, seals made from traditional materials, and the risk of carbon gum and varnish, you need to be sure that your oil will perform as the vehicle manufacturer originally intended.
With the most appropriate and carefully balanced additive technology to provide the best protection and performance for classic engines, Castrol Classic Oils are your premium lubricant.
Zinc Content:
ZDDP is an oil additive that comes with many myths and opinions attached
The average zinc content of Castrol Classic Oil is 820 parts/million average.
Normally 800 – 1000 parts/million is acceptable over all the grades.
A higher content of zinc ppm is recommended in Classic engines that are used for racing and competition purposes, but it must be remembered that the high zinc content of those oils can be very corrosive when the cars are stored or not actively used for any period of time.
Classic racers in the day would actually drain the race oil from their engines after competing as they were well aware of this issue.
Consider then the average Classic car in this day and age and its use on the roads now. Many tend to be weekend or even monthly or even less frequent drivers.
Normal daily driving of cars with high zinc content is not recommended by the technicians at Castrol.
For this reason Castrol do not recommend a very high Zinc content for oils in Classic cars.
