Default should i switch for winter?

i was thinking of swithching to 5w30 for winter, been using 10w30, but wanted to know if it will benefit anything, or should i just stick with the 10w30 i been using? this morning here in akron ohio it was 8 degrees, but our winters here are real wacky. it might be 50 degrees tomorrow!

If you check your manual, you will see that both are OK at 8 deg F. If it doesn't get much colder this winter, you should be OK. . If you anticipate a lot of very cold morning starts in the minus F zone, 5w would flow better cold and make it a little easier to crank the engine on a cold battery.

Are you using synthetic or conventional oil? If synthetic, either should be fine for winter (although I'd probably drop down to the 5w-30 or even 0w-30). If you're talking about conventional oil, I'd definitely drop down to 5w-30 for the winter.

I switch to 5w30 for the winter months and then go back to 10w30 for summer and use mobil 1. I switch during a regular oil change interval when it gets close to winter, or however it works out, and the same thing for spring.

^^I've been doing that for a while, although I've recently made the switch to German Castrol Syntec 0w30 all year around. The 0w30 is surprisingly thicker than even the M1 10w30 in the summertime!

Look at his car, guys. 5w30 might be a little thin for a 10-yr-old 1.8

nosajh9: You can try it but keep an eye on the level; it might burn more of that thin an oil.

I did notice his car but seeing how I donít know much about the 1.8ís I meant in general terms. Most my knowledge right now is with the wrx 2.0. I know for my car 5w30 is a bit thin but ok and will cause increased oil consumption. I would have mentioned that but seeing how Iím not sure about the 1.8ís I meant in general terms. And yes with 5w30 I do notice increased oil consumption. I do know that boxer engines in general will burn oil and as a rule of thumb check the oil level frequently. Iím not a guru yet but Iím learning.

i just changed the oil and put in the valvoline maxlife 5w30. i cant seem to find anything that says this is bad or good. maybe i should have just stayed with the 10w30. i guess ill just have to be extra careful and check my oil more often with the 5w30 in it. also, arent the "high mileage" oils actually a little thicker than conventionals with the same weight?

It depends on the specific oil and maker. High milage oils are very robust and have lots of detergents and other additives, generally a good thing.

MaxLife 5W30 (synthetic) is a tad thicker than M1 5W30 (even after M1 recently thickened it up). Castrol GTX High Mileage 5W30 (dino) is thicker than both. All high mileage oils aren't necessarily synthetic, fyi. Check the manufacture spec data sheets to compare thickness.
