Is a quality 5W40 just like another quality 5W40?
My 6.4L Challenger is a thirsty girl and calls for 7 qts of 0W40 synthetic. There's a lot of debate on this, because these were initially calling for 5W40 and have gone back and forth, officially, on the manual and the fill cap, and depending on who Chrysler had an oil contract relationship with and what was available at the time. I also plan to use this in the summer and temps are hot here, and year round rarely dip cold enough to be of a concern and this car is never taken out below freezing anyway. For my application, 5W is consistent with prior recommendations and largely irrelevant as I understand the differences are small between 0W and 5W, and irrelevant if the car is never operated in freezing temps anyway. Moving on...
Regardless, the local shop has this Chevron 5W40 that is heavily discounted at $8 per gallon and after current rebates, is free (well, the first 3 gallons anyway). https://www.chevronlubricants.com/en_us/home/products/delo-400-xsp-sae-5w-40.html
My game plan is basically nearly free high quality 5W40 for a lot of future summer oil changes on the 6.4L Challenger. I'm going to clean them out. I nearly bought it all today, but foolishly did not. Now I'm wanting to get some feedback and return tomorrow to buy it all.
The oil seems marketed heavily to diesels but also says 4-stroke gas motors (I am embarrassed to admit I'm not sure what that means, unless it's referring to not using 2-stroke motors like motorcycles and yard tools that consume a mixture of 2-stroke oil and gas). This big powerful engine seems like it would benefit from these additive packages for "heavy duty," running at high hard RPMs from time to time.
The marketing has phrases like this:
"Delo 400 XSP SAE 5W-40 with ISOSYN Advanced Technology is an API CK-4 heavy duty engine oil specifically formulated for on-highway and off-highway applications including 2017 greenhouse gas (GHG 17) compliant diesel engines with lower CO2 emissions and improved fuel economy, in addition to EPA 2010 compliant low emission diesel engines with Selective Catalytic Reduction (SCR), Diesel Particulate Filter (DPF) and Exhaust Gas Recirculation (EGR) systems. It is fully compatible with previous engine models and previous API Oil Service Categories. It delivers value through:
Promotes consistent cold engine starting for gasoline and diesel engines operating in sub-zero temps.
Exceptional soot dispersancy and wear control protect the cylinders, pistons, rings, and valve train components against wear and corrosion, promoting optimum service life and minimal maintenance. Contributes to maximum vehicle utilization and minimal downtime. Delo 400 XSP SAE 5W-40 with ISOSYN Advanced Technology is a mixed-fleet motor oil recommended for naturally aspirated and turbocharged four-stroke diesel engines and four-stroke gasoline engines in which the API CK-4 or API SN service categories and SAE 5W-40 viscosity grades are recommended. It is formulated for engines operating under severe service and a wide range of climatic conditions.
Delo 400 XSP SAE 5W-40 with ISOSYN Advanced Technology is excellent for use in engines developed to meet 2010 emissions standards and in engines equipped with features like four-valve heads, supercharging, turbocharging, direct injection, shorter piston crowns, higher power density, intercooling, full electronic management of fuel and emissions systems, exhaust gas recirculation, and exhaust particulate filters. It is formulated for exceptional performance with many fuels, including low sulfur and ultra low sulfur diesel fuels.
This product is recommended for use in older engines, as well as in today’s most modern low emission designs."
