I think you can mix them without doing any damage to the engine. I think you can even add a quart of synthetic oil to regular oil if your engine is low on oil. Generally you would want the 5-30 in an area where it is colder.

Can you mix Castrol Edge 10W-30 with Castrol Syntec 10W-30?
Yes you can. I spoke to Castrol customer service on 16 Feb 12 and asked if I could mix a left over 1 gallon bottle of the older Syntec with the newer Edge formula I just purchased. I was told as long as they are the same viscosity, they can be mixed.
Can you mix castrol syntec with castrol edge?
This is from Castrols customer service after I emailed them this same question... Our previous Castrol SYNTEC product has been improved, renamed and repackaged as Castrol EDGE with Syntec Power Technology (SPT) however it remains in a black bottle and is fully compatible for use with the previous Castrol SYNTEC product so as always, you can use the same SAE grade of either product together for 'topping off' purposes without fear. The new Castrol EDGE with SPT is not only as good as the previous Castrol SYNTEC product that you were using but better!

Can you use your soup mix 2010?
As of June 2013, it is not advisable to use your soup mix from 2010. The shelf life of soup mix is approximately 18 months, so this would only be a year and a half. The soup mix should be discarded and new soup mix should be purchased.
