Exactly! But don’t forget about the oil filter – replacing it regularly is just as important for engine health.

I recommend checking your oil every month, even in between changes. It’s simple, and it’ll help you catch any leaks early.

23

That’s solid advice! I didn’t realize how often I should be checking it until I read some maintenance blogs.

Synthetic oil does have its perks, but some people argue it’s not worth the extra cost. I say it’s an investment in your vehicle. What’s your take?

I disagree! Regular oil works just fine for many drivers. It’s about balance and what you’re comfortable with.

Don’t forget to factor in oil brand too. Some brands are more reliable than others. Researching reviews can help guide your choices.

Very true! It’s a bit overwhelming with so many options, but I usually stick to well-reviewed brands.

How often do you guys find yourselves checking the oil level versus just relying on the system alerts?

Honestly, not enough! I should probably start making it a routine. They say habits form in 21 days…guess I’ll try!

I use Mobil 1 synthetic oil in my 2021 Blazer, and it runs smoothly. I noticed a slight improvement in fuel mileage too!

I’ve heard good things about Mobil 1. Do you think it helps in hot weather performance?

I prefer Castrol Edge for my Blazer. I noticed it has better performance during those cold winter starts!

I’m using Pennzoil Ultra Platinum and loving it! No issues at all and the engine feels quiet and responsive.

That’s great to hear! I’ve read that it can help with engine cleanliness too.

I’ve had a rough time with Valvoline; it seemed fine at first, but I had some idling issues. Might not be for me.

I just switched to Amsoil and the performance is noticeably better! My gas mileage improved as well.

For me, I stick with the recommended Dexos 1 Gen 2 oil. It keeps things simple and I haven’t had any issues so far.
