I feel like this will be a stupid question but im going to ask anyway....

so mobil 1 changed esp 0w-40 to supercar 0w-40. I cannot find anywhere the correct oil to use now for the c7 zo6 is the supercar mobil1 0w-40. Just wanted to confirm and be sure 100% before doing my oil change next weekend. I have read the two are pretty much identical... so I have 1 qt of the esp 0w-40 from my last oil change... can i use that one qt with the supercar oil?... thanks!

 

The oil didn't change, but the label on the bottle and the color of the cap did. Too many people saw the 0W-40 on the Euro spec oil and used it by mistake, so Mobil fixed the problem with a label change.
Strangely enough, some sellers advertise the ESP formula at a lower price than the supercar, but ship the supercar when you get your order.

 

cool... just wanted to make sure... thanks...

 

 

For street duty, the Dexos1 or 2 rated Mobil 1 5W30 works as well. Here is what the 2019 OM says about the oil:Page 162
Engine Oil
The engine is factory filled with 0W-40 dexos2 oil. For LT1 and LT4 engines only, 0W-40 dexos2 engine oil is approved for both track and street use. 15W-50 full synthetic engine oil may also be used for track use, but after track use must be changed back to 0W-40 dexos2 for street use. If 0W-40 dexos2 oil is not available, 5W-30 dexos1 full synthetic engine oil may be used for street use. If 5W-30 dexos1 is used, it must be changed to 0W-40 dexos2 or 15W-50 full synthetic engine oil for track use. For the LT5 engine, SAE 15W-50 full synthetic engine oil must be used for track use, but after track use must be changed back to 0W-40 dexos2 for street use.

Z51 Performance Package, Grand Sport, Z06, and ZR1: Check the oil level often during track events and competitive driving and keep the level at or near 0.5 L (0.5 qt) above the upper mark that shows the proper operating range on the engine oil dipstick. After the competitive driving, remove excess oil so that the level on the dipstick is not above the upper mark that shows the proper operating range.

Selecting the Right Engine Oil
Selecting the right engine oil depends on both the proper oil specification and viscosity grade. See Recommended Fluids and Lubricants 0 321.

Specification
Use engine oils that meet the dexos2 specification. Engine oils that have been approved by GM as meeting the dexos2 specification are marked with the dexos2 approved logo. See www.gmdexos.com.

Page 237
Viscosity Grade
Use SAE 0W-40 viscosity grade engine oil. When selecting an oil of the appropriate viscosity grade, it is recommended to select an oil of the correct specification. See “Specification” earlier in this section. For the LT1 and LT4 engines only, if 0W-40 dexos2 oil is not available, SAE 5W-30 dexos1 full synthetic engine oil may be used for street use.

As mentioned above since the manual was printed Mobil has changed the name of the 0W40 oil to help avoid confusion among people that don't read all of the information in the owner's manual, Mobil 1 Brochures, GM Brochures and the information printed on oil container labels. So now we have SuperCar 0W40 = Dexos2 ESP 0W40.
