FAQ
THE ANSWERS TO YOUR QUESTIONS ON FUEL ECONOMY LUBRICANTS
1. Do Fuel Economy oils maintain their Fuel Economy character throughout the oil change interval?
Generally speaking, Fuel Economy oils undergo the same stresses as conventional oils and therefore maintain their Fuel Economy capability up to the next oil change. Where light vehicles are concerned, TOTAL Lubrifiants has chosen to use components least sensitive to alteration in time due to the effects of Fuel Economy oil.
2. Is there not a risk of losing the constructor’s warranty in case of a problem occurring on a vehicle when using a Fuel Economy oil?
There is no problem since TOTAL Fuel Economy oils are approved by constructors and their levels of performance are defined by the same constructors. The approvals shown on the cans ensure the user of a warranty on all points, identical to that offered for conventional oils of the same level of approval.
3. Are Fuel Economy (…W-30 grade) oils usable in very hot climates?
Yes, because the block temperature is always high (over 100°C) and coolers regulate the oil temperature to this level. The impact of the external temperature is therefore quite low. Tests conducted in India or North Africa have confirmed the excellent behaviour of TOTAL Fuel Economy oils. Moreover, TOTAL has developed a special …W-30 grade lubricant (RUBIA FE 20W-30) for heavy goods vehicles and buses in very hot climates
