Apparently Restore will restore your engine the the lump of metal it was before it became an engine.

Why would anyone put lead and copper in their motor?

Why would you like to use T6, it's a thick oil, it will effect your fuel economy, although I do not know of any oil this good and this cheap....


cause it looks like my vis. is on the lower side

I have to say that you've taken all the "drive by spankings" that everyone has insisted on delivering in their own little story of how they wouldn't have used Restore. It's kind fun to watch when it's not you. Sorta like seeing someone down on one knee ..so you kick other one out since he's in an indefensible position.

Your engine is going to shear any oil down to it's base after enough time in use. It won't continue to degrade below that ..'cept what fuel dilution does. Index your viscosity selection based on that.

I don't know if you need a snyth. You just have to do shorter OCI's imo. I'm talking about getting your RESTORE signature out of there. I can't see why a 15w-40 won't hold up for a shorter OCI. I don't think fuel economy is an issue with you. Otherwise, we'd be talking about a SOHC 2.0 NA instead of this. As far as cold starts, I'm sure that there are SRT Stage III owners in Billings MT or somewhere cold. I don't think your VA climate will trump that.

Most distinctions between synthetics and conventional break down to duration of use ..even at stress. After you get it cleaned out to the point where you can understand what's going on, then some highly additized or ester based oil would probably work best.

No matter what anyone recommends here, there is no OEM aspect to this engine. You're well beyond the envelope of conventional thought on the matter. Your power density exceeds (I think) anything that ever rolled off of a show room floor. At least with the size sump and cooling system you have.

Gary Allan,

It'll be okay to switch to conventional after 5 years of synthetic use? How short should I make the OCI's and how many do you think it'll take before all the restore is gone? What kind of brand conventional do you recommend for this process with my engine?

My suggestion would be to use Red Line but only after you do some other oil changes(shorter or not) to get the rest of the Restore out.

It would be ok to switch to conventional after 5 years of synthetic but if the owners manual states to use synthetic only use that. I would suggest you find some synthetic oil deals so you can save money if you decide to do shorter oil changes intervals.

Like Gary was saying, 15w-40 HD (dino) is always a good starting point in heavily modded cars. See how that performs for you and then see if you need to make any adjustments, with the 15w-40 as a reference. You may need a 5w-40 in Virginia winters though.

Different strokes. That's a turbo motor,so I would continue to use the synthetic and 3-4k ocis. Some turbos aren't even together at 78k.

 

[o2compressor]

hmm

If it was a sewing machine Honda you would continue to do 3-4k OCI's

If this was an OEM "as sold" car, he probably wouldn't be here. This is a Stage III mod. There is no Stage III reference in the owners manual for OCI's or oils to keep his warranty intact. The HTHS for the 15w-40's are about as good as you can ask for ..but if he wants to pay premium prices for oil he'll be dumping in a few thousand ..fine.

THe Stg 3 is a map sensor, bigger turbo, wastegate and cal and fuel pump upgrade. Do you have Toys?

A friend installed one a few years ago on a SRT, said it was awesome, ran real nice and made gobs of power I wish they offered a kit for the PT GT.

I would run whatever flavor of synthetic 5w-30 and change at shorter 3-4K intervals.

Keep an eye on your coolant and watch your fuel in the oil, sounds like they trim the stg 3 a little fat.

I have 2 2.4 turbos in PT GT's and few other Turbo Dodges.

What kind of fuel economy do you get if you take a long highway trip???

How is your transaxle holding up, keep the fluid in that changed, I run Amsoil MTF in my getrags instead of the ATF+4

Yeah, but my Great,Great Grandmom's foot pedal sewing machine is still in the family and runs like,well,a "sewing machine".................we just keep a long drip pan under it.

15w-40 HD is made for *turbo* diesels.

 

[TurboLuver]

I agree with Gary, run a couple of short oci's with conventional 15w-40, then run an oci with the synthetic of your choice and do a UOA.

Yes I have turbo toys. Those 2.4 PT GT's have the same motor but automatic =(. You can still buy a stage 3 turbo itself ( or similar), bigger fuel injectors, fuel pump, etc and just get a diablosport flash programmer and download a stage 3 tune. I'm not sure how the automatic tranny will hold up though. On the highway I get extremely good mpg, about 30. That's not boosting and staying at a consistent speed. Tranny is holding up well. I run Amsoil ATF + Mopar LSD additive. ATF+4 and Mopar LSD is what the manual states.

Alright, since you have the same car I will try it out. Any recommended brands? How short of a OCI and how many times before you think it's all out?

 

[VNTS]

THe two GT's I own have the 5 spd Getrag 288 in them.

If your getting 30 mpg highway, then I would say you probably have nothing to worry about. Run a 5w-30 and keep the intervals sane. AMsoil has some good 5w-30s. I dont see the need for a 40W. Keep up with the PCV and change it once in a while.

Per moding the GT, I could but I have too many cars to feed. I have Stg 1 on the 03 GT and I am not sold on the Diablos or at least the tunes for the PT's.

Try the Amsoil MTF in your trans axle, I think you would be surpised versus the ATF. Also dont forget your PS, I would flush it and put in some Amsoil ATF in it if you havent done so.

If it were me,I would just pick up some Rotella and run a couple of 2.5k mile oci's, then run a full oci with synthetic and send a sample in for a UOA.
I run a 40W synthetic in my SRT4 in large part due to the better HTHS properties that Gary alluded to earlier.

 

[o2compressor]

Only rotella 15w40 I found was the triple protection one. Is that the one?
