Wynn’s Oil Check List

Is the OEM oil spec still appropriate for your older engine?


Engine Oil requirements have changed dramatically over the years, moving towards environmentally acceptable, low SAP and catalytic converter safe oils which are becoming commonplace for our
modern vehicles, but are these oils meeting the requirements of your older high mileage car?
Older cars with high mileage often require a few extra ‘vitamins’ 20 – 30 years down the road as engine tolerances , wear and tear and general aging of components have long since exceeded the limitations of the original oil spec.

The Wynn’s Engine Oil Check list:

Noisy tappets and valve train
Older valve train and flat tappet type arrangements relied heavily on specific anti-wear additives such as ZDDP (vastly reduced in modern oils) to form essential sacrificial boundary lubrication between friction surfaces.
Wynn’s Hydraulic Valve Lifter Concentrate prevents contamination often associated with sticky valve lifters but also contains anti-wear additive ZDDP to protect and quieten noisy tappets and valve train.

Using oil – As an engine wears, friction and heat increases causing the oil to become thinner and less effective compromising film strength as well as allowing blow-by and oil seepage into the combustion chamber. Compression is lost and blue oil smoke is often the result of burning oil.
Wynn’s Charge is a Viscosity Index Improver to prevent oil thinning as temperature increases providing better oil film protection while preventing oil seepage past the compression rings reducing smoke and restoring compression.

Shrunken or hardened valve stem seals – Elastomer components deteriorate over time losing their ability to flex and seal as intended. Rubber/ Nitrile valve stem and oil seals are commonly the cause of leaks resulting in smoke, engine fouling as well as external oil leaking.
Wynn’s Engine Stop Leak is a Viscosity Index Improver with special seal nourishing additives to prevent not only blow-by oil loss, but rejuvenate hardened oil seals preventing further leaks.

Contamination –We all know that clean, uncontaminated motor oil is essential for today’s high performance as well as older engines and although manufactures are obliged to be ISO 9001 certified to ensure that their oil is 100% contamination free, deposits are formed under a variety of conditions such as high temperatures, fuel dilution and combustion gasses leading to oil oxidation and acidity. These contaminants form gums, varnishes and sludge deposits which immediately degrade any new oil when added to the system if not thoroughly removed before an oil change.
So why do we add clean “ISO certified” oil into a dirty engine?

For many years, flushing the engine oil was controversial as engine lubrication could be compromised, but with today’s advanced chemical technology, oil system flushing has become an essential part of best practice for vehicle maintenance as an oil system preparation for the optimal performance of new oil.

 Wynn’s Oil System Flush is specifically developed to meet the latest Euro spec vehicle and oil demands, performing complete oil system cleaning from the sump through to the narrow oil galleries while preventing wear.
Preventative maintenance is always best, so why not use a well-balanced Advanced Engine Treatment to boost the Total Base Number (TBN) preventing oxidation and sludge formation while providing a friction proofing for extra lubrication and oil efficacy, extending the oil life and increasing engine performance.
