Another dreaded Oil question.

[andrew_s]

So Im looking to change oils possibly from motorcraft full synthetic to either mobile 1 or mobile 1 EP or penzoil ultra. The mobile and penzoil both have outstanding reputations and are much cheaper then the motorcraft full synthetic. So in an effort to save some cash and possibly improve the oil in my truck (worst case scenario keep it the same quality) Im here researching what yall have used in yours.

Please no my oil is better, just state which of the ones listed you use mileage and uses and how you like the oil. Thanks yall!

i use valvoline full synthetic 5w30 i like the gaurantee they offer i change it 6,000 miles

I had been using Mobil1 5W30 in a couple of boosted vehicles that were notoriously bad on oil.

One was a Mazda CX7 sludge monster that was turbo and DI (fuel contamination issue). The Mobil1 was great, and when the CX7 needed some warranty work for their faulty VVT actuator (which would take out the timing chain, which would take out the whole topend), the whole top end was completely clean, no sludge, no varnish.

The other engine was a Subaru Legacy GT 2.5L turbo, that had a rep for blowing turbos due to sludge build up. I never had any engine problems in that vehicle (the rest of the car was a POS). I never had the valve covers off that Boxer engine, but if anything like the Mazda, I am sure it was clean.

My friend uses Mobil1 in his race car, a LT1 powered Firebird. The engine has over 2000 race miles and the top and bottom ends look brand new.

We bought the 2010 Expy EL used, and the dealer had just changed the oil. In December, I am going to do an oil/filter change, and switch over to 0W20 Mobil1. The 0W20 meets Ford specs for 5W20, and the other advantage of 0W20 is that it is thin enough at startup to actually give some initial startup protection. Check out BITOG, but there is a big write up about the advantages of 0W20 on startup, even in warm climates (I am in Texas, hard winter starts are not an issue).

I am sure Mobil1, PP, PU, etc. are all great oils, but I've seen Mobil1 first hand so I'm sticking with that.

 

[andrew_s]

Yeah I have been there and posted a similar thread on BITOG but got the "it doesnt matter at those OIC" statements. Reason Im asking here is the motorcraft is doing great in my truck but the most expensive oil I have ever bought and Im wondering what everyone's results are with the modular and mobile and pennzoil top shelf oils. Honestly when I worked for ford we always used the synthetic blend on literally everything and the modular engines didnt give a damn what was in it.

I will look and see about what the price difference is on pennzoil ultra and M1 EP and regular and go from there. I love how M1 is abundant everywhere so its easy to get oil, but with a walmart right down the street its easy enough to get whatever I need. As for the Valvoline I use that in my Jeep grand cherokee (high mileage dino) and everything has been perfect but that was because the engine had some rough miles and I didnt want to switch to synthetic at the time due to not having the time or money to deal with leaks or issues that arose.

Thanks yall for the comments and keep them coming as long as they are constructive and not bashing one oil and putting another on a pedestal.

M1 is $25 for 5 qt jug. So $75 for 15 qts (enough for two oil changes). Walmart price.

PU is $26 for a 5qt jug, and is supposedly a better oil, the BITOG guys seem to love it. May be a little harder to find.

In my turbo cars, I ran the M1 and kept the OCI to 3000 miles. My plan for the Expy is just 2x a year M1 since we only put ~10k/year on it. Like I said, I've seen the M1 first hand, I like the bottle design for pouring, and it's a little cheaper.

M1 gets my vote and goes into everything I own. Over the past 10 yrs, I've had multiple Fords from new and they all received M1 at 3000mi and then I stretched interals to 6-7000 miles. Can't beat autozone when the special comes around, 5.25 qt jug and M1 extended performance filter...$35

 

[superexpy]

M1 for me. I wouldn't put Pennzoil in anything ever!

 

[toms89]

I use Mobil 1 or Castrol Syntec.

 

[96mustangV6]

I'll probably get crap but I always use Castrol GTX 5w-30 iny navi. It has 220,000 miles and been doing great. I use Castrol Synthetic in the wife's MZ3. Just an oil I've always used.

Now in my dirt car we run Valvoline Race 50w. Motor is always taken apart for checking and everything looks brand new.

I know its none u listed but thought I'd throw them in. Always been happy with them.

Never heard bad about M1. But wouldnt run Pennzoil from just other peoples experience.

But it could of been there fault and not the oil. Most oils are about the same any more besides Lucas, am soil or others like that.

I would just pick one u feel comfortable with and run it.

My wife has had 2 hondas fed castrol gtx and one is at 100k and the other went 200k. The only 4eason we sold ot is she needed something bigger then a del sol for kids. So you wont find a castrol hater in me.

Im starting to recluse back into my mobile 1 self with alll these comments. Sure BITOG talk up pennzoil ultra bu m1 has been the life blood of many of my vehiles so might as welll stick with a tried and true oil plus its the same price as ultra and I'll have peace of mind. Not that its better but that its a known good.

From what I have read the modular engines just dont care about oil type just as long as you change it from time to time it will just run forever. I feel better about my purchase more and more everyday.

Waste of money IMO. Especially on a stock motor.

I ran Mobil 1 for years with no issues. Main reason I stopped was the Cobra had an oil leak and buying synthetic was getting expensive. I switched to Motorcraft semi synthetic and haven't had any issues with any of my vehicles. I change all the vehicles around 5k miles.

Found this surfing the web.

Cool test... gonna have a tough time finding most of those in the US...Those are Australian blends.


Since I don't know what was used on the last oil change or the history of this truck... other than a fram orange oil filter. I went with Amsoil OE this time and a Napa Gold oil filter.

When I get ready for the next oil change, I will pull a UOA and then decide. But the plan is to go with Amsoil XL the next time for 10k, then possibly the Amsoil signature for a 25k run.

Ditto on the M1. I also use a Mobil filter. I think it keeps the oil noticeably cleaner longer than other filters IMHO.

I get my oil tested every so often with Blackstone Labs. They show the additives still working at 5000 miles with regular M1 and recommended 6000 mile intervals. I am trying M1 EP this go and I'll have it tested to see how it looks. According to the test results, the 5.4 is still healthy at 140k and should last for many miles.

I like having Blackstone test the oil every so often. Being an independent lab, they have "no horse in the race" so to speak and will tell it like it is.

 

[andrew_s]

I need to find the sheet where it shows the ford modular engines being the least picky on oil. Basically the test said that the modular engines didnt give a damn what oil was in it so long as the oil was the right weight and changed on time.

Im going to do some more research on M1 EP vs M! regular and see what the real differences are as the price difference at walmart is negligible and for such little extra change I can have a slightly better oil. I still plan to keep the 5k OIC and I know that its over kill, but Im OCD about my oil and since I recycle it Im not feeling bad about using slightly more oil compared to a 7500 OIC.

As far as filters are concerned I use Mobile 1, Purolator pure one, WIX, and k and n. Also with now owning a ford I have used a motorcraft filter once and the only reaosn I may not use them again is that I have read the filter element on the previously mentioned filters are slightly better.

 

[whowey]

K&N oil filters are made by Champion Labs, just like a ton of other filters. Just get yourself a good quality filter and skip the fancy name and welded nut.

 

[GAINMOB]

Many filters may be made by a single company...its the specs that makes them different

My Expy has run nothing but Shell Rotella T 15W-40 since its scheduled maintenance ended. That’s all my father would put in it. It’s supposed to be for heavy-duty diesel motors, diesel generators, and construction equipment.

Since I took ownership, that’s what I keep in it. The Expy is closing in on almost 240,000 miles using the Rotella T, so I see no point in changing brands or grades now. It can’t be all that bad of an oil.

 

[JUST4FUN]

castrol gtx on everything from age of 16 and now im 47 never had a oil related problem ever even my tractor with a briggs 17.5 has 1300 hrs on it
