safe to use royal purple?
i heard a rumor and i just wanna hear the truth from the guys whom know best. I heard you could not use any synthetic gear oil for the transmission or the differential in my 88 turbo? That it would wear out the seals quicker than normal and that its too thin that it would slip through the seals. is this true? i never heard anything like that before. I know when you go synthetic you can't go back to conventional oil. I was planning to use royal purple. or do you guys recommend something better. Thanks guys!

you CAN swap. The only thing that hurts is changing the weight. I work at a lube and they had a big talk about swaping,or anything with over 100ks cant run syn. NOT TRUE! I run royal purple 1540 in my Z with 218k and it runs GREAT. BUT dont swap weights, it ok to go a little higher but dont go back down. We have people who run 530 in the winter and 1030 in the summer.
Now for what your wanting to know. Syn is a slicker man made oil. They wouldnt make it if you couldnt run it. Only thing i can say is to try it. But personally, i wouldnt run it unless it is NEW.

whats a good weight to use for the 88 turbo? i was gonna use royal purple 80-90 if i remember correctly. i currently have the the master pro performance 80-90 currently in use and its non synthetic in the differential and regular gl5 in the manny tranny.

Whatever weight the factory calls for, I have to use a thicker gear oil where I live though, as ambient temps are usually above 120 in the summer.

use high mileage oil. my prference is valvoline mixed with a touch of lucas. it may not be full syn but its def designed for those high mileage motors, trans, diffs, etc.... i worked at toyota for 2 years and they made us take a course on this basic stuff. if you have replaced seals then dont worry about it, use full syn. the high milage helps the seals swell up and seal better. plus its slicker than factory products too.

hey ronin i wouldnt believe hoov cause the turbo he was talking about is now mine and i did the diff and gear oil change two weeks after i got it and it was completly black and smelled horrible as a matter of fact it was so poorly taken care of only 4 out of the 6 spark plugs were good on that car but yeah i run synthetic and i have yet to have any leaks or problems.

You mean the diff oil I never changed in that car? you know, I've owned more then a couple z31's since the one I sold you.
(it's gear oil, it smells like **** regardless, Its funny you say that, as it had fresh oil, new plugs, wires, cap, rotor, fuel filter, trans fluid and coolant. The car was beautifully maintained, besides the diff fluid and ran great when I sold it to you, if its ****ed up now, its your own damn fault, don't attack me personally because your a ignorant dumbass with no experience)

you really think castrol sucks? I thought it was running good for me and from the guys at work said that castrol is the better oil than any other brands. But i thought it was a bad idea to run synthetic oil in a high mileage vehicle. im doing some regular driving daily with occasional racing on the weekend. i really want to use royal purple cuz that's what i run in my 400 hp 7th gen. celica gts. And its AWESOME! But what about in a high mileage Z?
#17
When choosing oil, why would you even think about that? oil isn't about making power, it's about protection and reduced wear. If your buying oil, because it "frees up hp" then you really need to learn what oil is and how it works.
#20
its a very good oil, its very clean, its very "Man made" and its worth its money. Now as for the HP goes, its proven it does, but i doubt you would feel it. Better mpg,cleaner internals,ect...........on n on .... if you would run it, you could tell US if its good

I am no mechanic, but I have try just about every oil on the market. I have been told that using Syn on the tranny is not good because is too slippery and you can miss gears, so I use regular gear oil on the tranny. One day I was reading about red line oil and how they created the necessary friction on their gear oil. I have several Z cars on my Z32TT I was using 15/50 then I changed to 10/30 and it seem I used a more oil so I am going to 10/40 I have used RP, V and Mobil I use mobil H Mileage. on Mt S130T I use 10/30 M , and on my 240z For mant years I used 30 so I decided to change to 10/30 Mobil and it run better now I am planing on using those new oils for older cars that have the "ZINC" that my car craves, why they took the zinc out ?
#23
THATS BAD! Shooting up and down the ladder like that. You dont wanna be going up and down in viscosity at all. For example, ya dont wanna be using a 20-50 then a 5-20 the next change. thats bad! a big no no
#24
I would not use 5/20 to me is too thin, but the new cars is what they use. if you say is bad going up and down I have never notice the difference I usualy do not think about rebuilting mu motors until the compression is low and that is usually over 200k. My Z32 is 245k and running strong, my s30 is just about 200k and does not burn nor use oil, my S130 is about 250k and it uses about a quart between oil changes and maybe a little more. The key is having clean oil to make it last brand and weight to me has no significant factor. do I run my cars hard , you bet they are Z cars why I would'nt?
#25
You're RIGHT there! Z Cars are meant to be run'd hard. I freakin love 'em! Ya the only one who really knows how well ya z car performs and therefore tune it the way ya know how it needs to be tuned. But i know for a fact running different types of weights off and on is really bad. Its like eating cereal every morning but changing out the milk everyday with something new. OJ and Cereal one day, next it could be beer and cereal. ehhh sounds like crap. Think of what ya car would say.
Ive always treated my z car as if it were alive. Something about it gives me a hard on every morning. Its best to stick by one oil and keep moving up in weight as it grows older. My Celica GTS lives, breathes, and bleeds only royal purple. And i plan to do a good old fashioned heart transplant into my 88T and revive my kick *** frankenstein livin and breathin royal purple through her veins. i know it works but it doesnt stop me from finding out what else does hence starting this thread on oil.
