Diesel oil is fine to use in gas engines. Diesel oil is superior to oil only rated for gas engines. It goes through harsher testing to meet the spec. Rotella T6 is a really good oil so it will work perfectly. I have used rotella T6 in many vehicles(cbr1000rr, Audi TT, F350 6.4 diesel, e.c.t) and i find it holds up really well to the extreme temps where i live (-40c to +40c)No. Diesel oil should never be used in a gas engine.
If you're looking for oil that meets the exact specs for the 1.4T, I think there are only 3, they're all from the same company, and only one is sold in North America (Pennzoil Platinum Euro). It's not a common grade of oil, and any 5W-40 oil that has at least an API SN rating should be fine. Most oil makers just don't bother paying FCA to meet the Chrysler spec, but if it's good enough for Porsche, BMW, and Mercedes, it's probably good enough for a Dart.I wouldn't run it. It's not like there's a shortage of oil for gas engines, so why risk it?
Interesting, as Rotella T6 5W-40 used to have API SN and other gasoline certifications. Apparently they changed the formulation and it now carries only diesel certifications. So, don't use Rotella T6 5W-40 in a Dart 1.4T.The "S" in "SN" stands for spark. It means that the engine is designed for use in gas engines, not diesel. I doubt an oil designed for diesel would have an SN rating
In regards to oil, his testing methodology is quite flawed. He tests flow rates using, what is essentially a slide for the oil to run down. He uses a coffee pot and portable burner to test evaporation. He uses a make-shift lubricity tester to test "film strength".... None of that provides conclusive proof of anything. His "test results" are anecdotal at best. His videos are entertaining, sure, but take the information provided in the videos with a grain of salt.While slightly off topic and I don't watch YouTube often I highly recommend watching ProjectFarm videos if you have any questions on oils, or lubricants of any kind. He does a lot of testing in conventional and unconventional situations and has a methodology that's just out of this world...for a dude in his garage that is!
I brought this up because shell rotella is actually in one of his videos. I'm unsure of the weight but it may be close to what your are looking at it not exactly the same.
Not all of us can get the Pennzoil 5w40 locally.....and not all of us want to order our oil online. I use Valvoline Full Synthetic European Vehicle 5w40 since it is available at my local Walmart store.....Pennzoil would be the better choice. Do NOT use diesel oil in a gas engine. Ever. Pennzoil is what dodge puts in the cars from the start, why not stick with it?
Not much of an option in Canada, since it's more than $130.00 for a case of 6 quarts and over $70.00 for shipping. I can buy it for $12 a quart locally, or I can wait until the 5L jug is 40-50% off on sale and pay under $40.00 for that. All dollar values stated are in Canadian loonies. If I've planned poorly, sometimes I will opt for Castrol Edge 5W-40. No, it doesn't have the Chrysler certification, but it meets the relevant BWM, Mercedes, Porsche, VW, and ACEA specs, which are all European. It would actually be odd to find a 5W-40 gasoline engine oil that wasn't specified primarily for European engines, since it's typically only used in European engines. American and Asian automakers tend to go with something like 5W-20 or 0W-20 (although I was looking at a Kia owner's manual once and it recommended the appropriate grade of oil with a table based on the climate).I just order the case of Pennzoil Euro Plat and either a Mopar or WIX filter from Amazon when I'm about 1K away from needing an oil change so I have it.
