Hey guys new to the forum. And to the 6.0 world. I am bullet proofing a 2006 f350 cab and chassis. Doing injectors and the whole nine yards. I live in Connecticut so we have cold and hot temperatures what are your guys in put on oil and what to use. Thanks in advance

 

Well, engine oils have come a long way since the days of old. Pretty much any diesel oil will work. However, some diesel owners prefer and swear by conventional oils, and some (like me) prefer synthetic oil and lubricants. I use Amsoil synthetic 5w40 engine oil. Its great for hot and cold weather. Ive used synthetics since I first bought my truck (mobil-1, rotella t-6, Valvoline premium blue, and Delo). However, 5 years ago I switched to Amsoil products, and bypass filter kit, and never looked back. Engine oils have been an on-going topic for many years. Everyone has a preference. If you prefer conventional dino-oil, make sure you change it regularly, as those Powerstrokes are really hard on oil. Synthetics are much more forgiving and will take much more abuse. I do really recommend using the Amsoil bypass filter kit. The bypass filter wll "scrub" the engine oil and remove the soot that can " thicken" your oil, keeping it cleaner longer. Cheers

 

I don't know of any 6.0L owners that are still running conventional oils. Bigg Redd is right, the bypass filter is worth its weight in gold for keeping the system clean and if you do UOA (used oil analysis) to extend oil change intervals, it can pay for itself very quickly. Keep in mind that this is a VERY controversial topic. There are some guys that will spend the $400 on a bypass filter, do the oil analysis, and still do an oil change every 5-7k miles. I'm not one of those guys. I'm at 12k miles (and counting) since my last oil change with UOAs still showing great results, the longest I've gone was 15k. It's no secret that the 6.0 shears oil because of the 4,000 psi the HPOP subjects it to, but it happens rapidly at first and then levels off, whereas some think that it continues to cut the oil down and will cause serious damage. When I first put on my bypass filter some 6 or 7 years ago, anything above 10k miles was uncharted territory and many of us were called crazy and stupid for even going 8k. There is SO much more information now and more and more people are starting to step out of their comfort zone to go further and further on their oil. The UOA is a great tool to get a look inside your engine and see what is happening before it becomes a problem, it can detect increases in certain metals, increases/decreases in flash point indicating that something is mixing with the oil that probably shouldn't be, silicon content that may come from RTV due to recent engine work or could indicate dirt entering the system.

It's good that you're doing injectors but I'm curious as to why. Many people replace injectors because of stiction...and many others go spend money on magic snake oils. Stiction is caused by the spool valve on the top of the injector hanging up until the oil is warm enough to fully penetrate, hence why it goes away once the truck warms up. The additives in the snake oil are thin enough that they can get into that valve sooner, the problem is, when you stop adding that stuff to your oil, the issue comes back. It "fixes" NOTHING. What DOES fix it is cleaning those spool valves...or replacing injectors. If you have already done the new injectors then what are you going to do with the ones you pulled out? I would be interested in having a set on the shelf for when the times comes to work on mine again.
