Pennzoil Full Synthetic oil Was wondering if anyone every tried this. Im probably gonna get some of these tomorrow, since it cheaper then mobil1. Also, if I get pennzoil full syn. 5w20, its safe to put in .5L of 0w20 mobil1 that I got left, along with the penzoil right? |
i have never put anything but Valvoline Synpower in my car and they claim 40% better protection for your motor than conventional oils. They do a lot of R&D and to be honest have a Maxlife Synthetic oil that also can prevent leaks by reconditioning your seals. Not trying to be a know it all but this is what i do for a living is change oil and prevenative maintinence. peace let me know if i can help you |
my friend used that in his 96 vic i think and it worked allright but my thought is that if ur goin full syn. the only way to go is PURPLE:rockon: |
royal purple. yeah but as far as i know there is no guarantees on royal purple or redline. |
its fine to mix the oils AS LONG as the specs are the same the motor specs that jumble of letters like sj for example if they both have the same then you're golden (at least one has to match and it has to be the one for your engine hehe) |

The important thing is to find one good oil and stick with it. Beside Mobil 1 has a tendancy to burn in Honda engines for some reason, I had this problem and I know quite few people have mentioned it. Other synthetic seem to be fine. But yeah, Pennzoil synthetic is fine.

Far quicker than any other synthetic oil, not sure why. But I only reccomend RP for race engines. Red Line seems to hold better for longer drain intervals. :shrug: |
royal purple is one of the "worser" synthetics you can buy. for the price they charge, you can get far better oil. that said, pennzoil, mobil 1, valvoline synthetics, etc, all are decent. Valvoline has a high tbn and will give you the longest drain interval as it sustains that TBN very well. if you're using synthetic, I hope you're waiting 10,000 miles between oil changes. if my S2000 can go 10k on valvoline synpower no problem (with UOAs that tell me there is STILL oil life left!) then your car can. also, while you can mix oils, you should try to keep the same weight among the oils you use. though .5 liter of a 0w20 vs a 5w20 should be ok. i have never put anything but Valvoline Synpower in my car and they claim 40% better protection for your motor than conventional oils. please read the sticky at the top of this forum. all of these questions are answered there by a true expert, and a greatly known engineer. edit: the links are temporarily down, but what i said above is the gist of it. |
Oh, I didnt know realize there was a sticky about oil at the top, but thanks for the heads up and answering my questions. |
I've used both full syn Pennzoil and Mobil 1 in Hondas and Subarus... didn't notice a difference between them. Looked the same going in and coming out. Haven't had any complaints about either. |
Thats good to hear. |
you can mix the oils even if their specs are different. pennzoil synth is a very good oil. |
yeah after further reading ctx66 is correct. but something else i found, is that you should mix oils from the same company. http://forums.s2ki.com/forums/index....owtopic=189631 10w-30 + 20w-50 = 15w-40. multi weights are compatible. As a matter of fact, synthetics are compatible with conventional oil. "the viscosities sum and then divide by total number of quarts = effective viscosity. I do not recommend mixing oils from different companies, unless you are adding one quart of syn to a minoil fill to get a synblend. Even then, probably better to mix the same company's min and syn." |
even mixing different brands is ok. motor oil is motor oil. a quick summary. around 80% of motor oil is a made from a base oil, ranging from group II to group V. companies regularly different groups of base oils to create a finished product. the remaining 20% of oil is an additive package. all motor oils across the board are the same in that they are mostly a base oil, and an additive package. the only thing that really is different between companies is the base oil mixture, and the amount of additives in the additive package. so there is nothing wrong with mixing different companies, they are fully compatable with each other. |
Anyways, I changed my oil yesterday, with about 850mL of 0w20 mobil1 and about 2.6L of 5w20 pennzoil full syn. The car ran smooth, so, so far so good. |
Originally Posted by ctx66 even mixing different brands is ok. motor oil is motor oil. in fact, the reason you should try to keep to the same brand, you even stated below. different addative packages and different base oil mixtures, since it varies between brands. while this isn't going to "blow up" your engine, there is obviously some reason NOT to do this, otherwise he'd have the same lacadaisical attitude about it you have. but he doesn't. if it's about oil, and he speaks it, chances are you can take it as face value period. in case you need reiteration, this is what he stated: I do not recommend mixing oils from different companies, unless you are adding one quart of syn to a minoil fill to get a synblend.

So you are saying all the addatives are compatible? I don't think so, infact they are often far from compatible. This is actually very simliar to blood, you and I both have red blood cells, white blood cells blah blah blah... But I am O- and you probably are not, so your blood is not compatible to mine, put your blood in me, I die. It's the additive like anti-foaming agents versus antiwear agents. The ratio of these two things interacts with the anti-oxidation additives, it's rather complex, and if you go throughing defferent additive packages together, you never know what could happen, it's the whole point to that Lucas oil treatment on bobistheoilguy.com. Point is these companies are spending millions to devolpe and produce additive packages, the additives are much more sensitive to varition than you are thinking. To think that every oil company has the same stuff and that they are interchangable just isn't the case. Multi-billion dollar companies are built around finding these additives and making them work in perfect harmony with each other, they aren't a mix and match game. |
been having troubles logging in, finally i got in and.. im talking an apples to apples comparison, mixing automotive motor oil. mixing motor oils with additives like lucas products is a whole different story. all additives in motor oils are completely compatable. you said you browse bobistheoilguy, look at all the members on there who make their own brews, and none of them have any problems. if you still dont believe me, make a thread asking if any harm can come from mixing different types of motor oils. synthetic, dino, blend, GF grades, api service categories, weights, etc. i think youve put too much thought into the lucas oil video, mixing motor oils just isnt the same thing. when you add concentrated additives to motor oils, bad shit can happen. because the base oil isnt designed to handle that kind of concentration of additives. however, when mixing motor oils, you do not run into this problem because each and every motor oil has a perfect balance of additives and base oil, so you dont get that extra high concentration which can cause problems. |

30+ year chemical engineer and tribologist (do you need to google what a tribologist is?) who's entire career has been nothing but automotive oil says: "if you mix oils, mix oils of the same brand as some addatives between the companies are incompatible" Guess who I'm going to listen to. kthxbye Unless of course you can provide credentials showing you know more about automotive oil than he does. :giggle: Dont mix oils from different manufacturers. the addin packs and addatives can be incompatible, causing the oil not to protect properly. |
