High Mileage Synthetic Oil?

yachtdr22 · 06-24-2014, 11:42 PM **Thread Starter**

Greetings all...
I just got a 2003 TJ w/ 153K
I am getting ready to change all the fluids and had a question about motor oils specific to a high mileage 6cyl 4.0.
I am a fan of synthetics and will be using Royal Purple in the MT, TC & TA
I am wondering what the best engine oil flavor to play with.

I use Mobile 1 in my 2009 tahoe???

Recommendations? whats your favorite recipe?

thanks
Drew

Can I delete this thread? I hate being redundant!

People will argue back and forth on engine oil synthetic vs conventional.

Personally I have always run Pennzoil platinum full synthetic with no leaks or problems.

All name brand oil is good, some slightly better than others. Anything will do fine in these engines so its really just personal opinion.

10W-30 for regular temps, for extreme cold use 5W-30

i knew that i could be playing with fire.. but... sometimes i have found it is worth it if i dont know!
I will likely go with the Mobile 1 high mileage 10w30
