Shell Rotella T6 Full Synthetic 5W-40 Motor Oil, 1 Gallon (3 Pack)

My diesel is getting old, no problems just wanted that little extra protection for summer months, always used the oil for 1999 F250 7.3 Diesel. Run around 6000 miles between my oil changes, I use a bigger oil filter than OEM Ford. I do put actives when changing. No problems with order. This truck was my work truck, and now my retired truck. 210K on it now and towed a car from Cal to TN with no problems, with the protection this oil provides.

I hesitated to switch from MotoCraft for my 2021 F250 Diesel for warranty purposes (drive train is 5 years). When I looked up qualified diesel oil meeting the Ford requirements, Shell Rotella was all over in terms of standard, semi-syn, and full syn. To top it off, Shell Rotella Syn picks up the engine warranty when the Ford warranty expires up to 15YR or 500,000 miles. WOW, I was sold. Don't forget to register for the warranty if you buy this oil.

I use Rotella T6 in all my engines, both gas and diesel as well as my farm tractors. For me, T6 is the ultimate lubrication. Having said that. this pail is white, not the usual blue and it leaked just a tad in transit. Not a deal breaker as the per pail price is excellent and I will purchase it again, just like I have in the past.Rotella in the 5-40 viscosity insures easy cold weather starts and performs excellent in hot weather as well.

Always arrives on time and it's the actual oil I trust.

I’ve tried different oil in my engine and Shell rotella T 6 gives consistent performance in mileage and particulate suspension.

There's not enough time in the day to explain used oil analyses or what the 5W and 40 mean. I can tell you that this has higher anti-wear additives than all the other oils you've been using. It even rejuvenates seals. I use this over "High Mileage" motor oil all the time. This rejuvenates my seals, reduces consumption, takes a BEATING, lasts a very long time, is always priced extremely well, made by Shell (whom also makes Pennzoil) and yeah.. I've ran this in cars for decades.It's worth trying. Research UOAs and see for yourself. I've seen better wear results from this than Mobil1, Pennzoil Platinum, etc. I won't name every brand, but it's got more additives because it's not pressured to keep the cats clean.News flash, if your cats are failing, it's not the oil's fault lol.

I use Rotella on just about everything.Good Price. Great Shipping Time.

Good price for a 3 gallons required in my 6.7 Cummins 2023 Ram diesel.
