hoodilio Posted July 23, 2003 Report Posted July 23, 2003 I am thinking about switching to Royal Purple oil in my 1993 Cutlass Supreme with a 3100v6, and i am just wundering if anyone has ever tried it, and if i should use 5w30 or 10w30. Quote
patgizz Posted July 23, 2003 Report Posted July 23, 2003 royal purple is the oil of the gods. i had a 97 chevy truck w/ 43k miles, switched from dino oil to RP and the motor ran so much smoother and quieter afterward. and w/ 17k mile oil changes it came out clean as it went in. i'm sold on it and wont use anything else unless its a beater.

Guest RedCutlassSL Posted July 23, 2003 Report Posted July 23, 2003 where does one get royal purple? is it better than mobil 1? Quote
hoodilio Posted July 23, 2003 Author Report Posted July 23, 2003 There is a race shop down the street from me in Billerica Mass thay sells it and you can also buy it off the internet. Quote
Aaron Posted July 23, 2003 Report Posted July 23, 2003 mobil 1 is jsut as good, my engine doesnt click at all with it, but it did with the sh!tty stuff Quote
gmrulz4u Posted July 23, 2003 Report Posted July 23, 2003 Yeah I'm a HUGE fan of Mobil 1 Tri-Synthetic...it's NICE... Quote
93Luminanewb Posted July 23, 2003 Report Posted July 23, 2003 I like Amsoil synthetic myself. It doesn't break down at all. One time when my dad hit a deer w/ our volvo, he drove it 7 miles (he turned the car off when going down hills though) with no antifreeze in the car. I think that's kind of impressive. Quote
Aaron Posted July 24, 2003 Report Posted July 24, 2003 uh were talking oil here bud, not coolant Quote
phantomFE3 Posted July 24, 2003 Report Posted July 24, 2003 hes saying the motor didnt get too hot because the oil inside kept it well lubricated and running smooth and soaked up some of the heat, without the coolant there to help it cool down the oil in the engine gets VERY hot and will break down and the engine will sieze because of all the expansion and everything, get it?

Aaron Posted July 24, 2003 Report Posted July 24, 2003 ah ok i get it. its just too late and maybe a little too much alcohol to jump to those conclusions. Quote
manitcor Posted July 24, 2003 Report Posted July 24, 2003 I use royal purple in both my engine and my transmission. From the first time I used it my engine ran smoother. RP claims that if you use thier engine oil, transmission oil and some other treatment they have that you can gain upto 10hp, I doubt thats true but I do know it has made things alot smoohter. You can sometimes find it in race shops and smaller independant parts stores, if you cant find it in your area just have a shop order it for you. Quote

The ferrari dealer sells it by my house i guess they use RP from the factory in all the new ferraris. - Justin Quote

hoodilio Posted July 24, 2003 Author Report Posted July 24, 2003 On one of the automobile television shows i watch, they changed all the fluids in some old clasic chevy (don;t remember wat it was), but they changed all the fluids to Royal Purple products and the dyno result with the RP products added 10hp.

SleeperRed90TGp Posted July 25, 2003 Report Posted July 25, 2003 If you have a high performanc cam don't use a full synthetic. Been through two of them and I have learned. A synthetic blend mayby be ok I don't really know. My Motor had 194k, .0015 taper in the bore, but .020-.030 wear on the cam. Just a heads up. Jud Yea for some reason I am a chatter box tonight!

Bake82 Posted July 25, 2003 Report Posted July 25, 2003 On one of the automobile television shows i watch, they changed all the fluids in some old clasic chevy (don;t remember wat it was), but they changed all the fluids to Royal Purple products and the dyno result with the RP products added 10hp. yah I saw that show too, I think it was a camaro, but still pretty sweet for just changing the fluids!! :shock: Quote
cutlassdude96 Posted July 25, 2003 Report Posted July 25, 2003 it was Horsepower TV with a curent gen Camaro Quote

SleeperRed90TGp Posted July 25, 2003 Report Posted July 25, 2003 Used pennzoil full synthetic for the last 10 years. Using regular 10-30 pennzoil for now or at least until I know the cam is ok. jud Quote
