Should I flush my engine oil before switching from conventional to synthetic oil or vice versa?

No, it is not necessary to flush your engine when switching between motor oils. Typically, conducting a routine oil change and replacing the conventional oil with a synthetic motor oil will not require any additional maintenance.

Do I need a special oil filter for a synthetic oil?

No, synthetic motor oil does not require you use a special filter. Oil filters are used based on vehicle specifications. Refer to your vehicle Owner’s Manual for guidance on what type of oil filter to use.

Is there a way to tell if my engine oil needs to be changed or is running low?

Yes, if equipped, your vehicle’s oil life monitoring system will inform you when your motor oil needs to be changed. Refer to your vehicle Owner’s Manual for more specific guidelines.

Does my transmission fluid need to be changed as regularly as my oil?

No, typically, transmission fluid lasts much longer than most engine oils. Refer to your vehicle Owner’s Manual to identify how often and when your transmission fluid should be changed. Severe usage and regular usage descriptions are provided.

Is there a difference between power steering fluid and transmission fluid?

Yes, there is a difference. There are many types of transmission fluid. GM Genuine Parts and ACDelco recommend referring to your vehicle Owner’s Manual for fluid recommendations for all vehicle systems.

Quality OEM diff fluid for limited slip differential on c6 corvette

Works great!

I bought this gear oil to replace the differential fluid on my 2018 Camaro SS and so far, so good! I mean it's OEM, so it better work! I had to buy a hand pump to get it flowing, but it was such an easy job, I think anyone can do it. The price seems to have gone up about $10 since I last bought it, but I think it's worth changing out if your car has never had it done before.

Fix for LSD clutch moan

2011 CTS-V Coupe, 57k miles. Had the dreaded clutch moan (sounds like tires rubbing) at slow speed, cold diff, full wheel turning lock. Drained old fluid, stabbed in new fluid. Few tight u-turns both ways, moan gone. 5 stars.
