anyone tried the new penzoil platinum which claims they clean 46% more of the engine gunk than any other product within the first oil change? very curious to know how the car feels afterwards? if anyones tried it post and tell your opinion.

 

Just another opinion from what I read at another site. Its one of the better syn oils and just a step down from amsoil.

 

yes, from bobistheoilguy, they are very good oils, so i stock 20L up last year. for my exp over the past year, these oils run fine on my 00 Maxima, and 00 TL, but only problem i found is that the oil lost for about 1/2L for every 4000km on both of my cars. not a big deal since i m changing my own oil every 6000km. after switching bk to castrol and mobil 1, oil lost disappeared, problem solved...

 

I use it in my wrx, it seems to work very well.

 

PP is one of the top-notch full-syn oils and it beats the crappp out of M1.

Amsoil is a good company for syn oils but I would not go Amsoil for engine oil, that is quite a stretch for the price. For average joe it isn't worth it from a price stdpoint.

UOA on PP are way better than M1 across vehicles on BITOG UOA forum and use it with full confidence.

 

they recently hiked up the prices of pennzoil platinum at wal mart...its now $23 for 5qt jug before it was $19...its still one of the best bang for the buck synthetics out there

 

I'd say ditch pennzoil and get Mobile 1 full syn. The best of the best. Penn will always be bottom of the barrel.

 

I wouldn't trust Pennzoil. I only use Mobile 1.

 

Oh really...

M1 share has steadily decreased since they moved their regular M1 (not the extended M1 which has some Grp4) to Grp3 base stock. PP uses better Grp3 base stock, no arguing here, UOAs are the best answer to who is better. Check them out on BITOG UOA forums. PP is nailing M1 across a broad spectrum of vehicles.

 

Pennzoil Platinum is a very robust oil that kills Mobil1 in Used Oil Analysis.

 

Yeah more and more UOA's show PP as well as some others above mobil1. I used to be all about mobil1 till I got my UOA now its only PP, german castrol, amsoil for my engine

 

M1 hasn't been the best in a long time. Might want to read up some on BITOG site.

PP is the best under Amsoil right now.

 

I just wanted to say that I just switched to pp from dino oil at 160k and it made the car run noticeably smoother and I have been gettin an average of 25more miles to a tank. So I think it's good stuff.

 

Some of the regular line M1 oils are good. Like the M1 0W-40, which is one of the few oils allowed for many European engines (it's ACEA A3/B3 rated, a hard certification to achieve).

But M1 0W-40 is probably not a popular viscosity with the VQ crowd.

You could also look into GC (German Castrol) 0W-30. This oil seems to do well on the UOAs.

Here in hot Florida, I've been using up a wide variety of some old stocks of oil in my VQ30 and sleep very well at night: PP 10W-30, M1 5W-30, AnyMajorBrand 15W-40.

 

Penzoil is junk it causes sludge build up castrol cleans or royal purple if you dont mind paying the price!

 

Prove it...!

What about Valvoline Syntech?

 

royal purple

 

Are you guys serious?? It was the cheap/local solution guys turned to with teh whole Mobile1 quality issues fiasco

 

During my last oil change, I used this oil with a Fram Toughgard oil filter. After 5500 mi, I did a drain, and had the oil sampled by Blackstone to find that it held its viscosity and didn't break down. I had to add a 1/2 quart to it between changes, but it didnt show any wear on my engine, etc.

 

Pennzoil Plat is supposed to be pretty decent actually.
It's $6 a jug cheaper than Mobil 1, next oil change I do I'll give it a shot.

Mobil 1 isn't even fully synthetic anymore LOL

 

First off PP and M1 are priced the same (Pennzoil increased their prices).
Second, M1 is a full synthetic oil, don't know what you characterize as full-syn. M1 is a great oil and has been for decades with a bullet proof additive pkg. Only recently they moved their regular M1 base stock to GrpIII.

Regular joe will always standby M1 since he knows nothing about the shortcuts Mobil has done recently. Only educated folks will know M1 is no longer the exclusive syn fluid with good results. PP kicks their butttt like no tomorrow becoz it uses better GrpIII stocks and an excellent additive pkg.

UOAs across different vehicles prove PP is better than M1, period.

 

Yeah, they probably are unfortunately. They are the reason that M1 can drop their quality and people will still buy it, name recognition. Ignorance must be bliss.

Pennzoil is still trying to clean up there name from the 70's, and they are doing a damn good job. You can bet they won't let it happen again.

 

works for me. oil still looks fairly new when drained @ 5k

 

PP and M1 are both group III base stocked oils. 0w-40 Mobil 1 is still a group IV base stock.

 

well my take on it is this M1 is still great oil sure they are GrpIII but the oil is still pretty good, I would say the PP is better cause of the better base stock but lets be honest either choice will protect your engine fine with your routine oil changes

In fact I just had an oil change done on my Acura RDX and just went with M1 5w30, for my wifes 03 Maxima I am gonna use XD3 until I run out of the stock I have.... Tommorrow I will buy a couple of 4.7 litre jugs of the PP, only thing I do not like to hear is many mentioning having to add some oil. To date with the Maxima I have never had to add any oil with XD3 or past M1 usage.

 

Anyone using the full-syn that Walmart sells for $18/5 qt jug? I think it is Q-State, has a Jimmie Johnson signature on it.

I bought a 5-qt jug of Mobil 1 instead, for $8 more ($26/jug) but I was tempted by the cheaper price.

Any synthetic is a huge step up from Dino oil, but Dino is still fine for the average driver who does 3-5000 mile oil changes and doesn't push the car hard (i.e redline it). Most folks, that's the category they fit in.

 

F that junk and get royal purple

 

LOL at the RP endorsement.

 

Been using M1 extended for a few years now and since I can no longer get it anywhere, I went with the PP 0/30 yesterday. I noticed the 0/30 jug says it has cleaning molecules but the 10/40 did not say that. I went with 0/30and the plan is to go 5k miles on this stuff using M1 108 filter (because I already had it)

 

I've had Castrol my first oil change since I got the car and I hated it!! Switched to Mobil 1 Extended Performance and it drove much better compared to castrol. My car is about 1k miles over due on oil with about 4,000 and I'm debating if I should stick with M1 or PP. I'm not too concerned right now because its only 4k and they claim to go up to 15k, so hopefully I'll decide soon enough. I like the pricing of PP ($23) as opposed to M1 at ($28.50). That extra 5.50 could go towards oil filter.

Anyone know if its bad to switch between oils? I have just about 157k miles so I don't want to do too many things with that much mileage.

 

It should not be a problem to switch between oils but I would say that one difference between PP and M1 Extended is that the PP is only good for 5k miles and you can take the M1 up to 15k miles. If you can get M1 Extended in your area then go with that and change the filter every 5k.

PP is not limited to 5K miles -- don't know where u heard this. M1 EP is the one that can take the vehicle for 15K OCI and regular M1 (that costs the same as PP, $23/5Q) does perform below PP in many UOA reports. One report on a VQ35..

For some reason I don't feel safe using oil for that long. Mine is dark brown right now so I'll be changing it soon anyways. Plus first 5 or so oil changes I'd like to change it around 3k just to clean things up. From the looks of things the previous owner did a horrible job maintaining the car. Car is finally starting to drive much better though.

 

maybe you should check the link I pasted before you make comments. I also said "extended" not "regular" M1 -get on board

 

If you are referring to the link you posted to AMSOIL's recently updated oil comparison (specifically the cost comparison illustration) AMSOIL selected 5K drain intervals for competing oils to illustrate the potential cost savings in using AMSOILs extended drain oils versus competing oils at more frequent (5K) drain intervals. The intent was not to state that those other oils could only be used for 5,000 miles.

 

Yes, I referred to the Amsoil report and my ealier post compared M1 Extended and not regular syn M1 as the poster missed.
Every oil in the Amsoil comparison, except AMS & M1 Extended showed a range of 5k miles which brought the cost of those way up. So my question is that if PP, and others, can go beyond 5k then why would Amsoil post that info?

 

Just guessing, but I suspect AMSOIL used 5K intervals to compare the cost of competing oils because those oils are not recommended for use beyond the OEMs recommended drain interval. In most cases, OEMs recommend ~3K drain intervals for Severe Service and 7500 mile intervals for Normal Service...5K (the number AMSOIL chose for the cost comparison) is at about the mid-point between the two service schedules. In addition, I believe most quick lubes will recommend 5K intervals even with a synthetic. So 5K for the competing oils (15K for Mobil-1 EP) is probably a good baseline for the purposes of this illustration.

It's been my experience, however, that cost is a secondary consideration when people switch to AMSOIL. Typically they buy the product for the performance and convenience it provides.

 

Interesting viewpoint(s), but I now find that the AMS Cost Analysis report has no relevance to any product. The report seems to indicate that PP and many other manufacturers suggest 5k oil change intervals and only AMS and M1 EP go beyond that. Now it appears to be BS. So I would say that it is just as fair to change the AMS and M1 Extended to 5k interval and redo the math for that analysis. This would shift the product cost of AMS to the most expensive as it loses its Economy of Scale (as they have done unfairly to their competition).
BTW not an AMS basher, been using it in my bike for years and think it is a superior product in comparison to HD SYN3.

 

Keep in mind that this illustration is designed to show how a person can potentially save money by using a quality oil with extended drain capabilities versus a less expensive oil drained more frequently. The difference between AMSOIL (and M-1 EP) and the competing oils is that only AMSOIL and M-1 EP are specifically formulated for extended drain intervals...the others all have to be drained more frequently. This is not a hard and fast test...it's an illustration. The length of time one chooses to use a product such as AMSOIL compared to the length of time they choose to use a less expensive oil (not to mention the number of miles one drives per year) will result in much different results of this comparison. But even if we were to give the competing synthetics credit for the maximum drain interval recommended by their manufacturer (7500 miles), AMSOIL at it's maximum drain recommendation would still be more cost effective. Reduce AMSOIL to 12.5K and keep the other synthetics at 7500 miles and AMSOIL is still more cost effective. Again, it's just an illustration...

But as I said in my previous post, most people choose AMSOIL for the performance and convenience it offers. In the big scheme of things, the cost difference is really not that much either way. I use AMSOIL because I believe it to be the best oil available, not the cheapest.
