Yes, an opinion if I may!
Please don't take this the wrong way...... Forums are great, and this one is excellent, but this info should be thought of as supplimental to your OEM information/specs! It is always best to get this for yourself, and for YOUR exact engine model and from YOUR OEM manual.
You don't want to become accidentally steered in the wrong direction due to miscommunication and/or misinterpretation......, bla bla bla!
This does happen, and the person who pays the price, is always the guy on the receiving end!
If you do take a suggestion, best if from a person with experience, and who has the exact same model as you have.
BTW, given the choice between the two heat ranges, be careful..... let your usage help determine this.
Some have issues with Champions..... personally, I don't use them.
