Anyone run 5W30 instead of 0W30? I took my warrior to the shop to have first service done last year and they put 5W instead of 0W - havent ridden it yet and that was the oil they put in when they summerized it. Do I need to change it to 0W30 or is 5W30 ok? They will change but cant get it to dealer before we leave. I might change the oil but not the filter if I get the chance. It is going to be about 15 to 20 below where we are going - Eagle River or Munsing.
Thanks!
Thanks!

No problem. I use 5w50.

I RUN 5w20...no probs.

He said 5w30 not 5w20 or 5w50, is there such a thing as these or did you guys have a typo? Anyway Yamaha had recommended 5w30 in the 03's then that changed to 0w30 semi synthethic. I think the only reason is for easier starts. Anyway the first oil change I used 5w30 and now I'm using 0w30. I wouldn't worry about it but would change to 0w30 semi next change. It's not that much more expensive when you consider changing it only every 2500miles or 5000kms.

You can buy just about any weight of oils you like. Want a 0w60? On the shelf. The higher the number, the greater the viscosity (more resistance to motion).
The first number, "0W", "5W", etc., compares the LOW TEMPERATURE pumpability (not the viscosity) against a single-grade motor oil. A 0w-anything will pump at a temperature as low as an SAE-0 (single grade oil with viscosity "0" at 100^C) oil will pump at. A 30w-anything will pump as cold as an SAE30. 30w30 is the same as SAE30. Note that the number is NOT the temperature.
The SECOND number is the actual viscosity at 100^C. Higher number is higher viscosity.
Higher viscosity means higher molecular cohesion - the oil will stick together better. Once the engine has warmed up, the first number is IRRELEVANT.
Also note; If 0w oil will pump as cold as -100^C (for example), then at 0^C, you DO NOT KNOW the viscosity. If you compare a 5w20 with a 5w50, both mineral oil, the 5w20 *probably* has lower viscosity at 0^C. If you compare a 5w20 mineral oil with a fully synthetic 5w50, the synthetic will probably be lower viscosity - for this reason, choosing a fully synthetic oil is better for cold starting than choosing a lower "W" number.
As far as semi-synthetic... all bets are off. Its really hard to tell whats really going on in them, but the specifications say "no more than 30% synthetic".... which means it can be less. And if you're going to pay more for your oil, might as well just buy fully synthetic - then you're not compromising the advantages of the synthetic.

great post LB!...
personally I went to a 5w20 FULLSYNTH...spoke to a redline rep and basically with synth they have tested their oils to be similar to the next higher number on top and also it will be easier at cold temps on bottom.
stock is semi at 0w30......redline SYNTH at 5w20 is the closest replacement in redline brand to stock oil...
redline rep stated that the 5 would be same as 0 on a semi,and the 20 would be same as 30 in semi...this is due to fact full synth will protect one size better(20synth=30semi) and also FLOW one size higher then semi(5synth=0semi)

If you read the back of the Mobil 1 container the 15W50 High performance driving formula pours at -45C
