Which oil is best?
#32
I was using Castrol GTX when my camshaft failed... At around 40k on the engine, 80k on the truck. It's what the dealer told me to use.
That was just after my extended warrantee ended.
After having the dealer and a few indy shops tell me I needed another new engine for around $9k or they'd buy my truck for $900 I finally started reading here and found a good indy mechanic and settled in on the Rotella 15w40... after getting a sweet deal on a new camshaft, lifters, timing chain and front cover .. and finding that I had succeeded in not killing my engine... I now have driven a further 80k miles with no further issues.
What I did not realize was that the dealer told me to use what they use... On current RR's and Jags in 2010 ish. Not flat tappet 4.6 V8's any longer. They stock oil for the current model... Here in my area at that time anyway.
I'm not trying to challenge you, just pass on some experience.
I've since had the HG's done and have seen the inside of my engine both after Castrol GTX and after an equal or greater amount of miles using Rotella 15w40... I'll take the latter.

I used Rot 15w40 in my D1 for a short time and on cold starts I had some valve clatter until the oil was flowing. I changed it out to 10w30 and it was fine.
I'm using Rotella T6 5w40 in my D2 now and it seems fine. I'm just curious if the 15w40 users are in warmer climates or what? I've always felt the 15w40 Rotella is one of the best oils out there but I just can't use it in a Disco with that issue I had.

you're choice,
some of us run the diesel type conventional oil, others synthetic.
this is why i run it.

if you can still see hone marks after a half million miles , I have to think it's working.
and Home Depot and Walmart have conventional oil it for $13.gallon.
