Nissan Consumer Affairs Oil Cooler Response

IDZRVIT · 06-06-2009, 08:52 AM

Nissan says/implies you can run all day with an oil temp of 279.9999999….. Above that, the car goes into limp mode. Because it’s Nissan’s warranty, they’d rather save money by protecting the engine from damage by going into limp mode than replace a damaged engine under their warranty. Lubricant technology has advanced and will always advance with improved properties of oils. Bearing materials improve also. Engine technology improves. Point is, this is not 1969 but 2009. Engines of today are not like the engines of yesteryear. Closer tolerances, improved reliability, advances in materials technology, coatings, better lubricants, etc.
So, for those still concerned about the oil temps I suggest this. Pony up a few hundred dollars each and hire a consultant such as South West Research or other firm that is internationally recognized in testing automotive lubricants. Pay for their expert opinions on your temp issue, offer up one of your cars for testing or whatever they recommend in order to present a qualified technical report on your issue. This will resolve your issue either in favour or not if the 260-280 temp is indeed a concern and that it will, beyond a doubt, cause catastrophic engine failure or premature failure of other components related to lubrication. Without concrete facts you have nothing to offer up to Nissan or the courts – law or public opinion.
Should the consultant agree with your temp issue, then present the facts to Nissan and demand that owners have their cars retrofitted with a suitable oil cooler. If Nissan doesn’t respond favourably, send the report to all the car mags, Society of Automotive Engineers and anyone else who has influence in the automotive industry. If Nissan still resists, class action suit to retrofit oil coolers.
In conclusion, get your FACTS first and then formulate the way ahead.
