The vehicle is a 2004 Ford F150-5.4L 3v engine used as a daily driver for 10K miles/year. I am currently using 5 qts MC 5W20 and 2qts Red Line 5W30, 5w20 not available. After reading UOA's about Red Line being "aggessive" re bearing wear I am concerned that my mixture is not such a good idea. Am I heading for problems with this mix? Thank you for your advice.
RL and MC5W20

How many miles do you have on this vehicle? How far do you plan to go on this interval?
I do not think that the MC/RL mixture will hurt anything. I am currently using the MC 5w-20 with the Schaeffer's Moly EP #132 and Lube Control (Molakule brew) in a Honda Odyssey.
Haley10 is correct about doing a UOA (used analysis) with Terry Dyson. The Blackstone TBN (total baseline #) with the Dyson commentary is the best deal going for $35. With this advice, you can fine tune the best combo for your truck.

The truck 7000 miles on it and my intention is to run 5K miles OCI. I will change at 10K miles and do a UOA at that time. The oil will only have about 3.5 miles use on it by then so maybe I should wait until 15K to run the UOA?
I am not "married" to the idea of 5K OCI, once every 2500 mile would be fine with me since I intend to have the dealership change it every 5K for warranty purposes anyway. Straight 5W20 makes me a little uneasy, particularly in the summer when 100 to 110 degree days are common. I add RL as insurance but I am not locked into RL, if something else will work I will be glad to give it a try. I have thought about adding a quart of Mobil 15W50 to 6 Quarts of MC5W20 at the next change. I do "over maintain" my vehiles,keep them 8-10 years, and have very few problems along the way. Thank you for your advice.

dbf,
I understand your worry about 5w-20. The MC 5w-20 (Conoco Hydroclear) is a top notch product. Do a search in Additives for "Molabrew" or "Schaeffer #132" and lubecontrol as well as "MC 5w-20" in the Used Oil Analysis Section; it has been a stellar performer. The #132 Moly will thicken up the MC to a 30 weight, however the MC 5w-20 is very close to a 30 weight oil anyway. The MC (ConocoPhillips) 5w30 is a semi-synthetic like the 5w-20 and could be used as a substitute if it makes you feel better.
The Redline 5w-20 by itself is similar in strength to many 10w30s, a good choice after the warranty period or the last option is Schaeffer's Blend 5w30 which is a Group II+, III with a superior additive package.
There are so many options available.

You will get varying opinions, I'm sure. One way to know for sure is to do a uoa and get Terry to interpret the results and consult with him on the matter. Otherwise, it's just opinion.
Personally, I don't mix motor oils. I might use additives that have Molakule's or Terry's approval for the application.
Without the uoa's, your brew is going to remain an unknown.
