Rotellat6 5w40 6*1 Quart Case

i have buying t6 full synth 15-40 for my two powerstroke 05 ford 6.0 diesel and 08 ford 6.4 diesel in my 6.0 engine i change every 2000 and at the most 3000 miles and because after 1000 the shearing is very noticable at 500 miles its completely black i now the 6liter are hard on oil but i have spent well in the thousands in oil changes just year rotella t6 nothing else

I've used the Rotella T6 5w-40 for years and years in motorcycles with wet clutches, trucks, and tractors and had no problems. Most notably I've used it in: 2004 Honda Shadow Sabre 1100 (wet clutch) and put 30k+ miles on it and I used it in my 2011 F-150 for it's entire life (bought new). The F-150 is impressive because it had the 3.5L Ecoboost, the first year of that engine, and I put over 218k miles on it with nothing done to the engine except oil changes and spark plug changes. I also use this in my tractors, I used it in my 2002 Dodge 2500 with the Cummins (bought new, sold at 168k miles), and other vehicles. I love this oil.

Iv ran a few different oils in my race bikes and ever since the switch from A recommendation from my father that has a gold wing with 90,000 miles no issues my race engines show very very minimal wear and tear in between seasons

This is a truly excellent oil that has the ratings and approvals for all my vehicles, gasoline, diesel, air and liquid cooled. Rotella T6 is the only oil I buy for my cars, trucks, tractors, ATV's, UTV's, ZTR's, gasoline and diesel powered generators, a power washer, log splitter and other small gasoline, air cooled engines, basically everything except 2-stroke gasoline engines. I love only having to buy one engine oil.

I have used various brands of synthetic oils on my 2006 F250 super duty 6.0 diesel over the past 10 years. I have not had the injector ECM reflashed, and in cold weather the engine sometimes chugs until the oil warms up. I attribute this to injector solenoid sticking. This cold chugging was noticeably reduced when I changed to ROTELLA T6.
