I used to use Royal Purple oil in my last car. Has anyone else used that in their truck?

 

I re-wrote my book the day I swapped my cam out

 

i think the 5w-30 recommendation is mainly for emissions purposes, but Mobil 1 5w-30 is good. so are the Syntec's, Royal Purple's, Redline's, Amsoil's, etc... as long as it is a good quality "synthetic" your fine. me currently Syntec 10w-30/Wix oil filter.

 

i use 5 quarts of mobil synthetic and 1 quart of lucas, top it off and change the filter at around 3k and change it at 7k.

 

nothing but amsoil in my truck. The chapioon store here sells it for 4.50 a quart. I had a 93 blazer that I used moble 1 in and it went for 210k miles and still ran when I traded it in on my truck. Ive also got a chrysler concord that has 110 which also services with amsoil.
I change it every 6000 miles and the filter every 3000.
I use wix filters.

anyone know what tranny fluid comes in a 2005 truck, and if you can use syn in it.

 

I use Mobil1 5w-30 in my 05 CC. I have only changed the oil once 1k. I am sitting at less then 5k now. I will change it out at 6k and then every 5k for the rest of the trucks life. I have a K5 blazer that after a motor swap 2 years ago I have only changed the oil once after the first 1k miles. (it has less then 10 k on it now) and the oil looks brand new.. Damn I love Mobil1... All that I have ever run.

 

Amsoil here, no problems so far..

 

Royal Purple, the cheap stuff ( 5.99 a quart) before my turbo. Now I run Royal Purple Race 21 (10.99 a quart) the oly reason I run it is because of the meth. I know the 21 won't be affected by the meth if some should find it's way to the oil pan.
Besides whats a 70+ dollar oil change anyway.

 

only for 81 plus thousand in this one

 

As long as it is a Dexron transmission fluid you can.
