Oil Question Again....

Points well taken Syn PSD.. No Harm nor Foul intended on my part

Each one of these PSDs has a Personality, no doubt.

The ONLY reason I went with Full Syn (Rotella T) was because I installed a by-pass filter.. To Costly to change Syn every 3K, a given.

I changed my oil last night and the truck started quite a bit easier this morning, not as cold as past mornings either though. We will see.

The bypass filter lets you extend your OCI, But running a oil blend is fine if i stick with my normal OCI without it? I've been changing my oil every 3k to 5k, like suggested by the dealer. I have a bypass system on my wishlist for christmas but currently do not have one.

IMHO "As long as the 2 oils are high quality oils, and the same brand of oils. I see no problems at all". Just stick to your normal OCI.

I've been using Amsoil 15W-40 in my 7.3 for the past 2 yrs and so far I've been very happy with the results. I have Amsoil all the way around in my truck and I've put in the Amsoil Bypass System which really has extended my oil changes. I do a lot of OTR driving, no hauling/pulling so that helps a lot. The bypass system wasn't cheap but I think it will pay for itself in a year and save me more than a few bucks down the road.

Whats the recommended OCI with the by-pass system and full syn. Is the by-pass system all you need or is there any additional stuff you gotta buy with it? I want to switch to full syn., but I want to make it last.

The recommended OCI on your 6.0 is when the lab says its time to change using Used Oil Analysis (UOA). Since the 6.0 is an oil shearing machine I would never go without UOA when extending the OCI. In my best guess with typical results you can expect 15-30k mile OCI using a bypass. Unlike the 7.3 which can use a dual bypass the 6.0 will use a single bypass used in concert with the oem filter.

Depends on which brand of bypass you buy as to whether you will need to get extra stuff. The Amsoil system I recommend will come with everything you need if you follow the recommendations as to what to get.
I would recommend with any brand bypass that you install a Fumoto Drain valve on the oil pan for making the collection of oil samples much easier.

I carry the Amsoil Products and Fumoto if your interested in finding out about pricing pm me.
