Twice ba ang speed ng oxidation ng OIL sa V8 than 4 cylinders?

[s_quilicot]

napansin ko kaninang umaga pag bunot ko ng dipstick sa e150 medyo maitim na ang oil ko pero 3500 kms palang natakbo nito and yung altis namin 7000 na tinakbo pero magkatulad lang sila ng oil sa e150. theyre using the same exact oil and same exact viscosity, both synthetic.

twice ba kabilis mag oxidize ang oil sa v8 than 4 cylinders due to additional displacement and cylinders?

does the displacement had to do with it?

TIA

It does get darker sooner since it also tends to generate more heat. When I had my lancer with the 1.5L 4 cylinder I could change oil and it would be a about 3 days of use before it would start to get dark. But with my Xterra with a 4.0L V6 it changes color after just one use of the truck. You have to remember with a V8 you have twice the cylinder count which would generate twice the carbon that the oil will pick up.

It's probably down to the design. The Altis engine is designed with tighter tolerances, so the potential for oil contamination is less.

Also, check your E150's tuning... from the sound of it, the engine is probably running pig-rich and the oil is picking up extra carbon deposits from the cylinder walls.

niky, what is pig rich?

sorry noob.

Drinking too much gasoline. The unburned gasoline is left as carbon deposits on the cylinder walls and washes into the oil. Some AFR tuning might help, but I don't know anyone who can tune a Triton.

depends how dirty it was before. if the engine of the ford was dirtier than the altis before then the new oil will get dirty faster since it is picking up all of the old deposits

nothing to worry about though.
