right now im using full sythetic 5w-20 should i use s thicker weight since i drive the car harder and has performance upgrades 5w 20 even though recomended just sounds weak to me.
Actually that is NOT true. The simple answer is NO! This is a common misconception by most vehicle owners, in fact the installation of aftermarket parts will not void the factory warranty. You are protected under the Magnusson-Moss Warranty - Federal Trade commission Improvement Act of 1975. The purpotrators are often new car dealerships not wanting to service your vehicle based on the fact that you have installed aftermarket equipment. This is fraudulent activity and must be brought to some official's attention to be remedied.Yes it will void your warrenty.
just use 5w30. ive got 165,000 miles on my zetec and its still runnin strong(well considering i need piston rings very soon lol)I run 5w30 in mine as well. Since that is the spec for the motors in Europe and the just thinned to 5w20 for Cafe standards in the US I prefer the 5w30. No issues in 126 k.
Well a thinner oil flows better, better flow can equal better heat dissipation, so ...
People seem to have this weird notion that thicker oil equals better protection, which is wrong. A thicker oil just puts more stress on the oil pump from it's resistance to flow (which is the definition of pressure, and many forget that).
The thicker oil just takes longer to heat because of it's lack of ability to flow. But with that it also takes longer to cool.
My vote goes for 5W-20 or 0W-20. There is no reason what so ever for thicker oil.
^^^ Sorry, don't mean to fight, but that statement is 100% wrong...
Okay, 80%...the stress on the oil pump is correct under cold starts, but other than that it is bad information...
