In order to extend the life of your engine, it is vital that the oil and filter be changed at the correct mile interval and with the right oil recommended by the manufacturer. Karmakanix stocks motor oil for all Audi / VW models with either 502.00, 504.00, 505.01, or 507.00 specifications, and for Porsche models with C30 and A40 specifications – all of which meet or exceed the manufacturer warranty requirements. There are big differences in quality between the various brands of synthetic oils, they are not all the same. Karmakanix only uses top brand lubricants as rated by Consumer Reports, such as Motul, Total and Amsoil. We also install only the best German oil filters. Certain engines will not survive unless the correct oil is used. The 1.8T motors are known for their demise from grit formed from incorrect oil and lack of oil changes. Modern diesels produced since 2009 MUST have 507.00 oil or the contaminants in the oil resulting from the regen cycles for the DPF particulate filter WILL damage the engine. All turbocharged motors including diesels, and all motors since 2005.5 require synthetic oil. Earlier motors will clearly benefit from the improved lubrication of synthetic oil, but must be slowly converted to synthetic to avoid leakage and possible clutch slippage issues. Most notably, VR6 engines will radically extend the life of the timing chain system when using synthetic oil with every oil change.
The Truth About Oil Change Intervals
Volkswagen, Audi and Porsche all recommend oil change intervals of 10,000 miles. It has always been a common adage that changing the oil twice as often as the manufacturer recommends makes the engine last twice as long. We find this to be essentially true. Most engines really should have the oil and filter changed around 5000 miles. There is great debate over oil change intervals. Some say frequent oil changes are worse for the environment, and that oil is still doing fine at 10,000 miles. We find that the problem is not so much about engine wear, but that the acrid components of old engine oil attack the plastic chain tensioners and guides present in most motors, eventually leading to catastrophic engine failure. We also notice that turbochargers tend to fail early when subjected to infrequent oil changes. Most early turbocharger failures occur between 125,000 and 150,000 miles in both gas and diesel models. We have verified that the majority of these turbo failures were in vehicles where the oil was changed at 10,000 mile intervals, or worse.
MoS2 Additive Engine Oil Additive
Of interest to those who are really trying to make their engines last, Karmakanix does recommend adding a Molybdenum Disulfide oil additive, known as Moly or MoS2, every third or fourth engine oil change. Moly is a friction reducer that is well proven to radically extend the service life of an engine. We are not so concerned about crankshaft to bearing wear, but scuffing components like the camshaft and pistons, and timing chains and guides are the parts that we see fail due to lack of overall longterm lubrication. Just mention Moly to your service writer to get it installed once a year. There is also a version for manual transmissions and differentials.
