FREQUENTLY ASKED QUESTIONS
WHY 15W40 OIL?
The old process used to separate engine oil was a chemical process which left many impurities in the oil. Today oil is cracked leaving very few impurities in the finished product. Our flat bottom lifters have the tolerances to allow for the impurities which are no longer present. By using 15W40 oil it takes up the space left by the absence of impurities making your engine feel tighter and stronger.
ISN'T 15W40 DIESEL OIL?
It is not the weight of the oil but the additives in the oil. The additive package in the 15W40 Collector Automobile Motor Oil is specifically engineered for flat bottom lifter gasoline engines without catalytic converters.
ISN'T ZINC A BANNED SUBSTANCE?
No. Zinc and phosphorus were reduced not removed from engine oils. The phosphorus, as it burns through the engine, coats and seals the inside of a catalytic converter, rendering it usless.
WHY DON'T I NOTICE A CHANGE IN MY ENGINE WITH MODERN OIL?
Because there is a build up of ZDDP in your flat bottom lifter engine; it takes about 2,500 miles for the damage to occur. By the time you hear the camshaft and lifters making noise, wear has already occurred. New rebuilt flat bottom lifter engines have no build up of ZDDP so the damage occurs usually within minutes.
CAN I ADD JUST ONE OR TWO LITRES OF COLLECTOR AUTOMOBILE MOTOR OIL (CAMOil) WITH MY OIL CHANGE?
No, each litre contains 1600ppm of ZDDP. A full compliment of CAMOil must be used, based on the holding capacity for your engine.
WHAT SHOULD THE OIL PRESSURE BE?
The rule we use (Keith Ansell of Foreign parts Positively) is that the oil pressure should be 10 Psi for each 1,000 Rpm of redline i.e.: If the redline of your engine is 6,000 Rpm you should have 60 Psi, 50 Psi with a redline of 5,000, etc. If these numbers cannot be reached using a 20W50 it probably is time for a new set of bearings.
WHAT WEIGHT OIL SHOULD I USE FOR MY 1953 TRIUMPH?
Pitman's Motorists Library by W.A. Gibson Martin 1953 THE BOOK OF THE TRIUMPH CARS: Oil Consumption. If, after a long periods of service, the oil consumption rises to and exceeds 1000 m.p.g., change to a grade of oil heavier than normal. One grade heavier is sufficient but in this matter advice form the Triumph agent would be helpful.
