Oil Change
 

Hey Kids, I just changed my oil 5 minutes ago with Mobil 1 synthetic 5w30 and I was just wondering if any of you are using the same. I figured since we all live in the same climate id ask if you step it up to 10w30 in the winter or just leave it at 5w30?

i use 10w30 all the time. i just allow myself more time for warm ups.

You have it backwards- if you're going to switch you want 5w30 in the winter and 10w30 in the summer. But with good synthetics, either one works if you're not up at the lake or ski resorts most mornings.

I don't change to any lighter or heavier up in Truckee but I have a garage both at work and at home.

Thanks BAN SUVS, so then my question is to anyone who hasnt already answered. Does anyone use 10w30 in the summer and 5w30 in the winter?

I used to use 0w30 in the winter and 5w30 in the summer. Now I use 5w30 year round, the slight mileage increase with the 0w30 isn't worth possible extra wear on the engine to me.

Anything from 0w30 to 15w50 (in the summer) seems to work just fine in our cars. The 15w50 is a little thick... but should be a little safer in the heat. On the other hand, I've been told that the 15w50 will actually generate *more* heat because it's so thick... go figure.

Either way, Mobil1 10w30 or 5w30 should be great in your car... it's not like your motor is seeing extreme conditions like endurance or drag racing.

That said, I use 10w30 RedLine in my car when it's working right, and Mobil1 5w30 or 10w30 (whatever WalMart's got in stock in the big cans) when I'm leaking lots of oil (since it sucks to waste $9 per quart that ends up in my catch cans).

Hah, yeah I'm the same way 5w30 or 10w30 based on which one I can find.

I've noticed its slightly harder to get the car started with 10w30 in the winter, and the temperature needle is slightly lower in all season (but more pronounced in the winter). Other than that, it seems like there is not much of a difference. The manual states (at least for the Legacy) that 5w30 or 10w30 is recommended based on climate and altitude. For our climate, I think either will be just fine.

I do. Not only is it hotter in the summer, but AutoX is during the summer. The manual says to use 10-30 for ambient temps above 100*F and/or heavy use, otherwise use 5-30. Mobil-1 in the 5 qt container at Walmart FTW.

Mobil-1 Costco 6qt Pak FTW

I think last time I figured it out, the 5 jug Wal-mart bottle was cheaper per quart than the 6 pack case at Costco.

I bet the price is pretty similar. But the costco is convenient because then you have an extra qt for between oil changes.

Really? I always thought having a big jug with the right amount of oil is more convenient than having an extra quart and a bunch of little bottles that are a PITA to fill up w/ used oil for drop off at Kragen.

Unless I'm changing the oil in the SVX, where a 5qt jug isn't enough oil. But then again, I buy 12 packs of Castrol for the SVX.

^ Oh i dont have to worry about that, I just pour it into my neighbors garden. Just like God said, "Blood and Oil are to be poured out on the ground"

Was God talking about Iraq?

Mobile 1 shouldnt have any negative effects on the engine should it? There are threads all over NASIOC and other forums saying that owners have had problems with Mobile 1. Most just state that there is a bigger problem at hand and using Mobile 1 in just a coincidence. Any negative effects from anyone here?

FYI I just changed my oil over to Mobile 1 5w30 synth. Is there anything special I'm supposed to do since I switched from conventional, like change it earlier than 3000?

I've been using Mobil1 since I bought my car over 60k miles ago. No problems that I could possibly attribute to the oil. If anything you can change it less often than 3000 miles. I do mine at 5000, and there has been testing done that indicates even up to 8000 miles is still safe. The filter is usually the weak point when using synthetic oil.

Yah, lots of spun bearings, but everyone on the forums use M-1 so it could just be a coincidence. I switched over to Royal Purple after reading the test results below and I got a good deal on a couple cases shipped to me. I'm running 5-30 in the winter and 10-30 in the summer.

Which reminds me. A 5qt jug of M-1 is $19.99 at Walmart rolled back from $23.99.

Well, thanx for posting those test results...maybe I will change my synthetic after my next oil change...

While we are on the topic, do you guys burn any oil? How much per change? I burn about a half qt per 3000. I also have 87,000 miles.

^My motor consumes about the same.

Hey Cody, where did that oil test come from?

Mine eats a little more than that.
