wondering if using 10w-30 instead of 5w-30 will hurt anything

[savibe23]

i put 10w-30 in the vibe and was wondering if it would make any dramatic differences in it. i know i shouldve stayed with the 5-30 but let my mechanic talk me into it. i have 92000 miles and its an 2004 1.8 rwd. let me know what ya think. all answers appreciated. thanks

Welcome to GenVibe!You MIGHT see a little decrease in gas mileage. That's the first thing that comes to mind. In TX you're probably not going to see consistently low enough temperatures (zero to -20F) that it could make much difference in cold-starting.

I agree. 5W30 probably still has a slight advantage at protecting (flowing) quicker when the engine is cold - but at the typical ambient temperatures where you are, you'd probably find it difficult to measure in any way.If the car's not consuming oil, I'd still choose to stick with the 5W30 - but either way, doing it regularly is most important. Keeping a good quality air filter in there, and a well sealed intake system will also go a long ways to keeping it healthy for a long time.I think that there are a lot of mechanics out there who just don't trust the "lighter" oils yet. He'd probably equate the 0W20 specified on my oil cap with water - although it's far from it. It will probably take a long time to change some perceptions though.John

time to do some reading.http://www.bobistheoilguy.com/cms/The oil depends on your location and what you do with your 1.8 (rwd)

Today's engines are engineered differently than the engines "back in the day" were.The clearances on the bearings are tighter and they spin easier using thinner oils. This is to increase fuel mileage by reducing friction.The most wear on your engine happens every morning and every time you start you engine COLD. Not bone chilling cold, cold from sitting cold.Oil is thickest at start up, it is harder to pump, it is thicker and doesn't flow.Can you use a 10 w ?? oil? Of course you can but realize that you may be doing irreversible harm to your engines bearings in the process.They don't invest huge amounts of money in engineering and then put that sill 5 w 20 on your oil cap for giggles.Use what they recommend. Sure it's a little harder to find and maybe costs a tad more but find it and pay the price.Dave

You won't see any difference fuel mileage or otherwise for a long time. The first number is only relevant when doing a cold start of the engine. Thicker oil will take longer to circulate causing slightly more wear on internal components.You should stick with the OEM recommendation or go even lighter to 0w30 if it even exists or you can find it.

I wouldn't worry too much about the 10w30 especially down here. I get all my oil from my dad who happens to be a Conoco Phillips distributer and in all our 4 cyl. we used to through in 10w30 if it was lying around and never had a prob. However i do usually run 0w20 or 5W20 but thats what the cap on my 09 calls for.

First thing I would do if I were you:find a new mechanic, fast.

Stick with the recommended weight, I'm switching to 0w-30 but I live in the cold weather!

Last week I put 10w-30 in mine,its summer here,temps arent getten beow 50deg now,I'll go back to 5w come winter.
