How to Change the Oil in a C7 Corvette Dry Sump Z51 & Grand Sport

You could just take the car to the dealer or search "oil change near me" on the web, but you can fairly easily (and much more cheaply) change your own oil! This step by step how-to guide will walk you through what you need to change the oil in any C7 Corvette Stingray with a Z51 package. The same exact procedure is also followed for the 2017+ C7 Grand Sports as well. (links below)Show more

UPDATE ON OIL: Since we filmed this video, GM has also approved the use of Mobil1 0W-40, which is good for both street AND track use! Pick it up at Amazon at https://amzn.to/2PaGNhs or Walmart at http://bit.ly/2PEvPAr.

Clarification on Oil Filter tightening:

There has been a lot of question as to whether the 22 ft-lbs figure for the oil filter is correct (which is what GM's repair manual says), so we went straight to the source to get a final answer. Mike Kociba, Assistant Chief Engineer of Small Block Engines, General Motors, says this:

"The service manual does indicate 22 ft-lbs, and can be used. This is a safe, and in some situations overkill, way to proceed. The manual of 22 ft-lbs differs from the factory method because specifying torque and angle for service complicates assembly, as it is hard to monitor angle with hand tools. Furthermore, using a pure torque specification on oil filters is tricky because there are many factors involved, such as thread friction, gasket friction, ease of access, presence of oil (or lack of) on both surfaces, etc.

That said, when applying 22 ft-lbs, two full turns of the filter after contact may result, especially if the filter gasket and mating surfaces are oily already – dry would require less rotation. In other extremes, 22 ft-lbs may only yield ¾ turn, which is also enough.

There are two alternatives to the above:

1. We use 10 Nm (8 ft-lbs) + 150 degrees for initial assembly in the factory.

2. Use the method that I, and millions of others, use: Spin the filter on by hand (no tools!) until it makes firm contact with the mating surface. By this point, effort has noticeably increased to turn the filter. Now, rotate the filter another ¾ to one turn (I do one full rotation to be safe). Helpful hint: mark the filter with a sharpie so you don’t go past one rotation. This method takes some “feel” – might be less to more expert mechanics – but is effective if done properly."
