Hard towing and PP

Status
Not open for further replies.
I picked up both the shell 5w40 synthetic and some PP 5w30 and im going to run both for maybe 5k under hard towing this summer and then I will have them both tested so we shall see how it all plays out?? I will use the same brand of filter as well and also keep track of how many miles of towing on each sample.

I just changed the oil with the Shell this afternoon.

Thanks for all the advice.
 
We switched from Schaeffers 9000 5W40 to 5W30 and it seems to work fine in our fleet of Ford E350s. I wold consider this a good choice also.
 
I'm going to be using Pennzoil Platinum for my next oil change in 5W-30 grade and I'm willing to bet it won't consume a drop of it. It has never consumed oil with any other oil I've tried (Valvoline, Amsoil and Havoline) and I'm not expecting this to be any different. We shall see!
 
"It definately isnot as good as M1 becuase it does fall flat on it's face in a nember of key area's. TBN retension,flash point and consumption are all important factors when looking at an oil. So just to be clear so no one thinks I am a PP hater. If I hated it so much I wouldnot 8 or so OCI of it sitting in my pole barn!"


Again, please provide data to back up your statements.....
 
Would there be any benefit of using RTS in a vehicle that calls for 5w20 (2005 F150 5.4 50,000 miles)? Truck is in so Cal, used 95% as daily driver, and 5% towing 7500 lbs.
 
Ford's 5.4 loves 5W20 oils - mine runs great on it and will get some valvetrain noise when cold using even 5W30, let alone a 5W40.

I like thicker oils in motors that is helps and use RTS 5W40 in 2 others, but have stuck with PP 5W20 in this motor - it has 73,000 miles and never burns a drop on 5000 miles OCI's

What are your oil sump temps when towing compared to when commuting? If they aren't significantly higher when towing, I would doubt you need anything thicker than the 5w20 it is spec'd to run.
 
Excuse me, I am no expert or oil chemist, but 5w-30 PP does not shear handles fuel dilution very well and I have seen plenty of UOA's that has good tbn retention also. It is a group 3 oil as far as I know. M-1 whatever the chemistry is a good oil, but plenty of UOA's have shown comsumption also. I would have not used PP in air cooled equipment anyway, most call for 10-30 rotella or 15-40 rotella can be used. 5w-40 rts has shown some great numbers in trucks with diesel engines and so so numbers in cars. It just comes down to what you drive. I have never had any comsumption with PP ever.
 
PP 5W30 does shear, has issues with consumption wich means it is going out the tail pipe not just the oil either but all the additives that are in it as well and it falls on it's face in the TBN and Flash point departments!! We have plenty of UOA where it does all of the above. SHow me a a single UOA in a engine that is in a good state of tune that has had it's consumption go up runing RTS5W40 as compared to wht it was running before or that has had a low flash point with 5W40RTS or that has had any issue at all of TBN retension not being up to snuf. Now find me two or more where all of that has happened in a single vechile runing RTS5W40. You can not do it! Because it has never happened! RTS has shown plenty of great numbers in gasoline engine the problem is too many people pass it over and we do not have a large sample size on this board of gasoline engines running it. Most of the one that have tried it had issues they where trying to fix like old worn out bearing with excessive clearance or massive oil consumption etc...... In every case that it has been run in a car it has either produced the same results as the prev ious oil or better results then the previous oil in terms of wear numbers. It is not going to make a GM engines wear profile match that of a Toyota I mean it is not a MEssiah in a bottle it is just a an excellent oil for the money. It is perfectly suited for use in gasoline cars even with small engine but again to many thin oil NAZI's and closed minded people on this board. If you want to prove me wrong then do an OCI with some. Even in gasoline V8 trucks that called for 5W20 the 5W40RTS had wear levels that where basicly the same as the same engine with the recomended 5W20 the difference between the two was in the noise level just a few digits either way. SO how is it that a 5W40 and a 5W20 can both work so well in an application recomending a 5W20 fromt he OEM. In most cases owners do not even notice a drop in fuel economy. You get better TBN,Better dispersant package, better AW package and an oil that can outlast almost any 5W20 that is sold OTC for $4 a quart.

So now after I run Bruce's 0W10 I have to make sure I run something like RTS 5W40 or Valvoline SYnpower 20W50 just to contrast. Bet you a dollar my thick OCI will turn in some crazy good wear numbers and good TBN!
 
John I never said Rts 5-40 was a bad oil. Never said PP was perfect also. People can go with their gut feelings and be happy. I have no desire to look up past Uoa'a on Rts 5w-40 and battle over tbn and that stuff. I am not defending any oil, my point is that PP is a very good oil, just like M-1, but I have seen few if any thinning issues with it and over the years few issues with M-1. By all means use Shell's Rotella synthetic for your applications. I might try it myself in something. You are a well respected member on this board and I have learned from your posts but to call people who use or favor thin oil's NAZI's is very poor choice or words. You know what Nazi's were, and I don't think we have Adolf Eichman or his buddies on this board. Gosh it is just oil.
 
PP is a good oil,but for towing i'd sleep a little better at night if i had a HDEO in,RTS is a good choice,another good one is M1's TDT 5w40.

By the way I run the shell between 5 and 6K under easy use.

We beat the heck out of PP 10-30 in the race engine with excellent numbers and no shearing at all. This with severe fuel dilution. Use it with absolute confidence.
 
I am not sure about group V oil. I think it was known as a EOP base oil from Shell. Now a group 3 like most otc synthetics, it holds it own very well. Interesting GrampsintheSand that you had those results. It would seem to me the high level of Calcium really does the trick for the aw package. Johnny could talk further on the composition of this oil.
 
For the abuse PP did very well.

I have not had ANY type of consumption in any of the vehicles I am using PP in. I've got two daily drivers that are pushing 6 months and the oil is still on the full line.

You, too? Everyone I know has the same experience with PP.
