Mobile 1 10W30, but Coednaked convinced me to go Amsoil next change.

Redline oil for the driveline.

 

I run 5w-30 Royal Purple every 6k the good stuff.....

 

whatever they put in at the dealership.

way too lazy to change my own oil.

 

Just about the extended life Mobil W at Wally World for $22 for 5 qts. Seems they only carry 10w30 tho.

 

Mobil 1 5W-30. I change it every 5000 miles, which is about once a year.

Penzoil Platinum is the best over the counter synthetic out now.. many many many UOA's to prove this even over M1. look on bitog.. if i were to pay full price for a syn it would be for PP.. i would not hesitate running 7-8 thousand miles on that stuff with a clean air filter.. its the best bang for the buck out now excluding sales..


btw i buy Valvoline Synpower buy one get one free at advance auto and run 5-6k miles with it.. check your local stores.. they have these sales atleast twice a year if not more. dang good deal

 

you running a synthetic? btw the info on 10w40 (if not a synthetic) is off... that weight may actually do more harm than good in the winter on cold start ups.. if you want to stay in the 40w area go synthetic in 0w40 or 5w40.. in the mtns of NC it can get pretty cold and stay that way. this is were synthetics really come into play bc of its great cold flow properties.. for the summer run whatever you want.

 

I've had pretty good luck with M1. I may look at the Pennzoil though.

 

Switched to M1 at 150K after Valvoline 5W-30 for its entire life. I did it just to see if there would be any problems with switching to synthetic, such as leaking oil etc. There have been no issues and I now have 162K.

 

get on BITOG.com and read the differences in M1 and Penzoil Platinum.. you will drop M1 also. way overrated.

 

How about some links instead of having to spend time looking for these specific comparisons?


I'm curious since I've seen nothing with torn down engines in person that would make me change from M1.

 

I run synthetic mk.....thanks for the info.

I use Valvoline 20 50. Anything lower viscosity and my oil light flickers at idle! My motor must be tired, no metal in my oil though, so hopefully I can keep her running well!

 

Mobil 1-- just a few here.. if you want to see more then go to bitog.com

Penzoil Platinum-- best syn for the $$ out now, plus the dino version is great too. they have came a long ways.. there are many more uoa's on the site praising PP.

This one is Schaeffers-- pretty decent report. look at the wear #'s compared to the previous mobil 1 uoa's also you have to look at miles on oil

nothin but castrol gtx for me and the previous owner...so it's been gtx for the life of my truck...which is 160k miles. sometimes i even debate on changing it at 3k miles b/c it is still golden-brown in color...but i do it anyways...

 

Unless you make a lot of short trips you could probably extend your interval a bit. I just put some Castrol GTX 5W30 in myself.

 

yeah if your commutes are normally 15 mins and longer or most of your driving is highway today's dino oils can easily go 5k miles in these motors.. so have no fear in going 5k miles on a good quality dino oil..

 

Royal Purple 5w-30 and the bigger Mobil One filter M1-209)

 

so after reading all of this i normally use mobile1 but i am thinking about switching to Castrol synblend, along with strickly amsoil air filters since i am still running a Fram Airhog and i cant even find recharger kits for it anymore..
anyhow would this be a wise switch?

 

A thicker oil can hurt things. It is to thick at start up.20 50 is thick it doesnt flow at start up thats the most crucial time.
