How does a new auto loan affect my credit score?

[Anonymous]

I was just approved for a new auto loan last week. It will be the first and only installment loan on my credit reports because my previous car loans/mortgage loans have already fell off. On everything I look at, it shows adding an installment loan will help my credit and score. Is this true? It's not showing up on my credit yet and I'm starting to feel alittle nervous about what will happen. Can you share your experiences with me? My current scores are in my signature, my credit will be 2 years old in August. My utilization is 12%. My DTI will be about 30% with the car loan.

My TU08 was 778 just prior to the new auto loan reporting. It went down to 774 afterwards, I have no prior auto loans, only just student loans for installment.

My revolving util is kept at 1%, and i honestly have no idea what my dti is (the monthly payment amounts of my student loans are being wonky on different reports, some are deferred, etc). My AAoA is hovering just above 5 years, but I have a pretty thick file with a very long "total" history.

So for me, it didn't have too strong of an effect either way.
