hey guys
i want to put in some motul 300V oil into the engine which cost lots of $$$
just wanted to know if the nulon oil flush affects the new oil in anyway???
for example, add nulon oil flush into engine with old oil, drain and refill with new oil
if theres old oil mixed with the oil flush still in the engine, can this make the new oil change its properties like make it thin???
Yep thats pretty much the case...
If you want to be 100% sure its gone just chuck in a fill worth of cheap multigrade oil and go for a lap around the block before adding your good oil.
When you're using the engine oil flush stuff just keep an eye on the oil pressure because if your engine / oil pump are getting on a bit your oil pressure could fall to a point that could damage the engine.
