Only diesel engines can use this particular Shell synthetic oil.

Shell claims that it increases fuel efficiency by 1.5% when compared to motor oils with an SAE 15W-40 viscosity. Rotella T6 is formulated with special substances that guard against grit and debris. This oil as well withstands viscosity loss, which aids in maintaining oil pressure. This synthetic oil is my favorite choice for diesel engines and is approved for use in a range of diesel vehicles, including tractors and heavy-duty pickup trucks.

Can I put this in a 2005 Volkswagen Golf Tdi?


For specialized needs, I would advise consulting your instruction booklet.

I myself own a Suzuki 1300 motorbike, a Suzuki 1200 motorcycle, a Honda Goldwing motorcycle, and a Ford diesel 4 cylinder tractor. Goldwing 10w-30, both Suzuki 10w-40s, and the 15w-40 that the tractor specifies are all suitable. Even better than conventional oil, I’d say. I have used…

Any suggestions for a 1979 Ford E-150 chateau?


• I used to think that adding synthetic to an older car would cause leakage. Well, I just went ahead and attempted it a few years back. Several trucks have less than 200k miles, others have more than 300k, and one has over 500k! all created during the 1990s. The one that did use a little oil in between oil replacements did not get any worse, neither did the others.


Could my monster moto minibike use this oil?


• In accordance with the requirements established by the tiny bike’s maker. Glance at the owner’s manual’s classification. My Gl1800 has Jaso MA listed as the specified location for this oil.


For the third generation Ram Eco Diesel, does this satisfy MS-12991?


According to several studies, this oil was generally regarded as one of the top six choices for the most recent Ford diesel engines. I am familiar with Rosella’s other non-synthetic diesel oils and know they are excellent as well. The typical huge chain car parts stores were great places to find this oil.

I switched from Mobil1 to this Shell Rotella T6 oil after noticing that I was losing more oil in between oil changes. The Mobil1 is too thin, it gets past the turbo seals, and as a result, it burns off, according to the few well-known Subaru forums. I started using this and I can definitely tell when I use less oil.

I’ve been using this fully synthetic oil in my Ford 7.3 liter turbo-diesel for a while. Every 5,000–6,000 miles, I change it, and I never require to add any in between. With more than 300,000 miles on it, it holds up incredibly well and the engine is still performing flawlessly.


Superb oil, this. It functions perfectly in my Honda 250L that I use.

  1. It costs less than some of the best motorcycle oils. Every 1,200 miles, you can replace the oil without going broke.
  2. It is suitable for use with wet plate clutches and fulfills motorcycle oil benchmarks.
  3. You can see it when you require it; when moving in far-flung parts of the world, you occasionally can’t find rigidly Motorcycle Oils.
  4. You will change the oil according to plan because of its affordable price. To save money, put no more than a few hundred miles on the oil.
  5. When the engine is cold, it begins easily.
  6. The engine operate very smoothly and with less vibration when traveling at highway speeds (I have no idea why; it just does).
  7. A 3 gallon carton can be purchased from Amazon for $70 while the same amount of top motorcycle oil would set you back more than $120.
  8. The oil is entirely synthetic. Why spend more money on mineral oil when you can get this for virtually as little?
  9. A good deal.
  10. A lot of motorcycle riders vouch for this oil.
  11. This oil makes motorcycle transmissions much smooth and easy. No more switching “Clunks”


  1. With this oil, the engine will wrap up much more smoothly and not quite as quickly.
  2. The general performance is only marginally better than the most expensive motorcycle oils, which run $60 per gallon.
  3. If you race, invest in the priciest motorcycle oil. If you’re a regular rider, this oil is ideal, affordable, and readily obtainable.
  4. If you can’t get the ideal motorcycle oil, it’s useless.

This Oil is peculiar since it runs like mercury while having the viscosity of sirup.


I’ve used this oil for 12 years on 5 motorcycles, 3 cars, a 2002 Honda Accord with over 200,000 miles, and for the past 4 years, a 2014 BMW 335d (diesel). The motorcycles range in size from 400cc thumpers and inline-4s to 800cc V4 motorcycles. have never once experienced an engine issue in any of them. Never, ever, any form of leakage. When I replaced the oil from the former owners, my motorcycles ran and shifted much more smoothly. As long as the temperature doesn’t go below the specified limit, this oil is almost always affordable, therefore I don’t know what it can’t do. 0 degrees is the lowest temperature I’ve directly encountered whilst using it (F). amazing stuff

Excellent performance in my 2003 Suzuki SV650. Strongly suggested. Compared to other oils, I ca n’t imagine how smoothly my bike now shifts up and down, clicks into gear, and revs out.

Just to reiterate what many people already know (and DON’T KNOW) about this oil: It is indeed JASO DH-2 & MA/MA2 approved, and the bottle bears a stamp designating it as a motorcycle-specific oil. This indicates that both dry and wet clutch applications are secure.

T6 5w-40 is certified for use with the Volvo VDS-4, if you look around. Shell does not publicly state this, however in order to comply with this specification, it must have an HTHS viscosity (Greater than) >3.9cP.

The bike has never operated or shifted as smoothly after a year and two T6 changes. My bike never hesitates to upshift or downshift as it should, even in the cold, all winter long and into the spring/summer (quite mild a swing of only 40F to 80F ambient). Just before replacing the oil, everything seemed excellent after 3k miles of brisk commuting. Unbeatable motorcycle oil T6 is showing to be, and at such a low price!


The only thing that I use in my 2005 F250 powerstroke which is used in Colorado. The changing temperatures in the state are ideal for this oil.

Wilson, J.

This has NEVER needed to be supplemented. I tow a big fifth wheel across the US with my 2014 Ford F-350 Diesel before performing routine maintenance. And when, midway through a drive from California to Northern Montana, the “oil change necessary” indicator illuminated, I continued on to my destination—another 700 miles—because?

I was confident in the durability of this synthetic lubricant and unconcerned about engine failure occurring before I reached my destination and changed the oil. I rechecked the oil when I got to Whitefish, and it was still full! My truck has 40K miles on it, largely from towing, and this most current trip was under unusually warm weather for a considerable distance—100° and even hotter, yikes.

Fantastic stuff! And such a terrific deal for the pricing on AMZ!

Bjorn Abner

I have a scooter maintenance business ran out of my home. I use roughly 4 gallons of T6 per year. T6 enters the crankcase if the bike has more than 1,500 kilometers on it. I apply this to everything, including 400cc Burgmans and 50cc Zumas. T6 has been in some of the bikes I work on for the majority of their more than 30,000 miles of use. A discount of $7.00 per gallon is typically offered. Absolutely fantastic oil at a fantastic price.
