Default 10w-40 for 1996 Saturn

Hello fellow Saturn owners and experts ...

I have a question about oil weight.
Like every Saturn I've owned (and every Saturn I know of) ... The Saturn I just bought burns oil.

I have always been skeptical to put anything, but 5w30 because of the big "5w30" printed on the oil cap.

The last time I topped up (about a half Qt.), I used 10w40 and my oil level is great.
No oil burn at all!

I am really tempted to just use 10w40 with my next oil change.
I figure the car is 12 years old ... it should be ok?!?

I have seen a few discussions, but noting that I can be confidant in as a definite yes or no on 10w40.

REWARD EXCELLENCE!

Even maybe 10W30.

You can switch, and you should not have a problem. IF you are in a area that gets cold, below freezing, maybe for now stick with 5W30. For me, in the summer i will use 10W30 and in the winter like now, 5W30. I dont think the 40 weight will be to thick, but you engine may have to work a little harder and may loose .5 MPG.

i was running 10w40 during the summer, this oil change (friday) is going to put me back at 5w30, it's been getting cold here, and most of my driving is early morning and late night.

I believe there are higher milage oils out there that are formulated to puff out gaskets to help stop leaks and such. Dont know much about them myself, probably because I stick to the cheap stuff... and my saturn doesnt burn oil lol.

I do know that you can run 30weight in 20weight vehicles and be safe. But like 1994Saturn stated, you might see the effects in milage.

As to the weight to use and why go here and read all of this carefully. http://www.bobistheoilguy.com/aehaas/ There is an incredible amount of FUD out there as it relates to the oil weight to use and why. This is not rocket science but you do need to educate yourself to be able to cut through the smoke.

Maybe you found the right combination of 5w-30 to 10w-40 mix to control oil useage!? As 1994Saturn mentions, if you live in cold weather country your engine will definitely have a hard time cranking over as using all 10w-40 will turn to molasses and make it very hard for the starter to turn. Why not use your new found formula instead, 3 1/2qts 5w-30, 1/2qt 10w-40, for the next oil change? Or 3qts 5w-30 and 1qt 10w-40? The first recipe for cold weather (freezing) to allow easy start-ups and the second one for warmer regions while still retaining the ability to use less oil? From one of these two starting points you can gauge how your engine handles the slighty heavier oil but still have mostly 5w-30 for all around coverage? You won't be risking making a mistake if 100% is all 10w-40 and the engine suffers starting with thicker oil. Who knows, maybe you stumbled onto controlling oil burning without having to rebuild? I'm sure there are some who'd be interested in the general health of your engine, mileage, region where you drive, etc., to compare whether anyone else can modify their oil blends to lessen oil useage. This can also turn out to be just temporary too but there's always room for experimenting...........

Luke has run his 95 SL2 for years on straight 30w and 10w40 oils, he has over 500k on his engine and gets around 40 MPG....

Id say 10w40 will work just fine in a Saturn(weather permitting) may need 10w30 in the cold weather....

I just changed out the 10w40 Exxon Superflo in my Bonneville today, 10w30 Mobil 1 for the winter. That way I just need to check it/top it off until springtime...(should be around 6000 miles til next change)

...
94 Blue SL1 RIP Thanks to a Drunk Uninsured Driver

Soon Ill be back in Saturnland.....

No. The Saturn S-Series Owner's Handbook says do NOT use 10W-40 oil. 5W-30 is best. You may use 10W-30 in warm climates and 0W-30 in cold weather but not 10W-40. They printed "5W-30" on the cap for a reason. The Saturn Owner's Handbook also addresses oil consumption.

Just an FYI ... I've been using 10w-40 for about 6 months (2 oil changes) and it is working GREAT!!!

Car preforms great ... 30MPG ... And Oil doesn't burn any more.

I know there are a lot of skeptics, but I don't care what you say ... 6 months and only good results.

For the record I live in Sacramento, CA where it can get cold, but not cold enough to snow. I can't tell you how it would work in EXTREMELY cold winters.

Manual states that you can use 10w-30 oil as long as it is above 20 degrees F. I'm sure it wouldn't look pretty when the extreme cold sets in.

Default Re: 10w-40 for 1996 Saturn

Oil consumption means ZERO wrt how the oil is actually performing as a LUBRICANT in the engine. The problem with anythingW40 is that it requires a LOT of viscosity improver (VI) additive to attain that viscosity range. More VI means less actual lubricant. This is why, as Eric mentioned several months ago, Saturn specifies that you not use it, and why GM stopped specifying it years (or is it decades now?) ago. You're better off with an oil that burns a little, knowing that it's lubricating properly. If you have a consumption problem with 5W30, try 10W30; it will probably not burn any more than 10W40, and having a narrower viscosity range, will be a MUCH better lubricant.

That old specter of "oil burning BAAAD, no oil burning GOOOOD" just won't die.
