Oil change intervals.

[js197]

Only true for conventional oil. A high quality synthetic oil is not usually effected by a colour change, 5,000 km or 6 months.

really? any oil I have beat on has turned black prematurely.

ive used just about every synthetic brand canadian tire sells at some point (usually whatever is on sale) only had my stang a year so it has only seen one brand so far.

from what I have read on the s197 and other US forums extended oil change intervals seems to increase odds of screwing up cam phasing on the 3v engines. I believe there is a filter that does not take kindly to sludge/debris.

2 oil changes a year vs potential engine issues? i think i will just do the oil changes.

I'm talking about the oil. I agree that the 4.6L 3V does not like extended OCIs BUT it is not the oils fault. Just because a synthetic oil is black is not a good reason to change it. A true synthetic can take a lot of abuse and still be perfectly capable of protecting the engine. Amsoil XL and Signature Series are 100% capable of going beyond 10,000 km on 1 OCI.

I'm old school. Don't care what dealer/manufacturer says....change every 5000 km!!!
