What's your engine oil?

[byron84]

I'm due for an oil change, previously I was just going to the dealer and it was something like $40 or $45 but it was whatever oil they put in, I didn't even think to ask. I know some people may be proponents of Synthetic and others stick to regular oil (well it's definitely cheaper).

I am thinking about going synthetic myself, I never have but know some people who have and swear by it.

My question then is, how to choose which oil to get?

you will be ok, if the car is running ok. I would be weary of doing it again though.
The step to 10w-40 would be ok. but 20w-50 is quite a jump, how hot is your climate?

Around 88 degrees F but with the humidity it get seriously hot! Temperatures have even exceeded 100 degrees!

[petrified.rabbit]

is that all the time?

The engine doesn't "feel" the humidity the way people do. 88F is 88F - no humidex applies.

That's some thick oil you've got in there, I'd say.

@petrified.rabbit: most of the days throughout the year it's like that yeah... Rainy seasons can cool down to approx. 75F...
@MetroMPG: Very thick, as I've checked... drove the car for like an hour and so far no probs... in fact, since the oil's new, albeit thick indeed, the drive feels somewhat better... I sure hope those guys at my friend's shop know what they were doing!

I've stuck to whatever the dealership puts into it. I get my oil changes free for life (as long as the dealership sticks to it's current ownership), so I can't really complain all that much. IDK what I'd use if I didn't get those free oil changes though.

Castrol GTX High Mileeage 5w30 and pureone filter for 7500 OCI. Thes cars are so easy on oil I feel bad dumping it. It comes out same thickness as the oil I put in, just darker. Used regular GTX till about 80K.

I've been using Amsoil 5w30 since the second oil change along with a Napa Platinum filter. At 180,000 km and it uses no oil with 10,000 km change intervals. Engine cranks well at -40 without using the block heater. Cost is double of dino oil, but so is drain interval - so overall cost is the same and I have better engine protection.

Been using Pennzoil Platinum in my cars since I've been driving. However, I am probably going to start using some high-mileage stuff in the Aveo come it's next oil change.
