Long story short, my trucks is due for its first Oil Changes this weekend "For Me, 2nd owner", my plan is to switch over to amsoil, my intent is to use a bypass kit in the spring of 13, but for now just switching to a synthetic will have to do.
my question are...
what oil additive shall i use ( if any)?
are the worth the extra $$?
if so who makes the best quality additive?
I also plan on doing the Allison spin on as well, and recommendations for that filter?
its a 2006 LBZ with currently 42000 on it.
For your 06 LBZ you will want to use 15W-40 Diesel and Marine oil
from AMSOIL and their EaO52 oil filter. The oil is a full synthetic heavily fortified and designed for the older diesel engines requiring 40 weight. This is also an extended drain oil.
If you are not interested in an extended drain you should consider AMSOIL OE 15W-40 Diesel oil
. This is a full synthetic AMSOIL came out with in 2011 for individuals looking for a high quality synthetic but not interested in extended drains.
The EaO oil filters
are some of the best on the market offering filtration of over 98% of all physical contaminants down to 20 microns plus 2x the capacity of an OEM filter. Combine this with the oil above and your drain interval is up to 3xOEM (about 22.5k miles) or 1 year, whichever comes first. Guaranteed by AMSOIL. When you consider you are running 1 oil change over the life of 3 conventional oil changes you are saving money and I can help you with the pricing you see on the AMSOIL site, saving you an additional 25-35% off that.
No oil additives are required or recommended. The only thing I would consider it flushing your motor with AMSOIL Engine and Transmission Flush
to clean up and sludge, vapor, varnish, old oil left behind from previous oil changes.
As far as filters go I offer filter packs from both WIX and Allison. If I can answer any questions, please don't hesitate to ask.
Amsoil is the best. Suggest using XL. I have been using it for 12 years in all my engines. Learned how good it was when a tech left my wifes oil fill cap off her Toyota 4 banger and found out after a 1600 mile trip with no engine damage.
I do not use additives, no need. Change about 10,000 miles, not 25,000 in a duramax until you get the bypass system.
I became a dealer also due to how good it is, but not looking for business on this forum.
You won't go wrong.
Drain intervals for XL are 10k miles or 6 months with any filter.
I would not recommend XL oil in a diesel engine as it is not formulated for use in diesels.
I run 15w-40 Diesel and Marine in both my LBZ for 1 year. I average about 20-25k miles on a single oil change with no problem at all. In fact to prove that the oil was still good for continued use, I did two oil analysis over the a yr time frame and ended up putting 28k miles on a single oil change. I could have continued to run the oil but I chose to change it out.
