I plan on using Havoline 5W20 when it comes time to change my factory fill (Honda Ridgeline) and I am using LC20 and FP60 right now. I intend to continue to use these products because I need a little extra to get my oil to the 6 or 7 K mark (that is about when the OLM puts out the service due notice).
My truck has no OCI interval as such and the warranty will be covered if you OCI by the OLM service due notice, or one year, whichever comes first. Lube Control says using LC20 can extend your OCI to 10K but that may be under ideal situations. Since you are only going 5K, the Havoline should do you very nicely all by itself - the LC20 would be just added protection.
