Synthetics and motor smoothness

Ok, I got one for you guys. I have a Protege 5. 2L motor/5 speed, and I drive the stew out of it. I put Royal Purple 5w-30 in it at 5000 miles and now have 6600 miles. In the last 100 miles I have noticed the motor is running a lot smoother. This motor is known for vibration - very noticable at 3000 RPM. I never had to look at the tack to check RPM, but now I do. Really smooth up to 6500 RPM. I have been running synthetic for years (Mobil 1) and have never experienced this. Engine just breaking in? Synthetic oil? RP oil? Too many beers? Sun in my eyes? [I dont know] Phil PS - the P5 is a HOOT to drive around the twisties very fast [Big Grin]

I beleive you are experiencing vertigo in those twisties there [Smile] I have never heard of a motor oil change helping balance a engine,don't think it is possible . Do those motors have a counter balancer in them? This is the first I have heard of that model having a vibration problem. By chance is it simalar or the same as the Focus motor? Anyway, glad you found a oil you like. [Cheers!] Many like the Royal Purple but I have no experience with it other than the Racing 11 in a T5 Transmission. I am curious why you chose it when you have used Mobil in the past. Did you have a bad experience with the Mobil or just bought a new car,try something different type deal like me?

Royal Purple contains moly, so I believe the smoothness is coming from that. I noticed my engine is smoother now since I switched from Maxlife to Schaeffer Supreme.

My engine was noticeably more vibratious on the M1 10W-30, and is quiet as an acura on the Maxlife 10W-30.... For a Camaro 3800-II to be this quiet its almost obsurd, but I'm happy.

Hey Dragboat - Vertigo - Lol. Man, sometimes I wonder [Eek!] This 2L has no relation to the Focus motor. Same specs but is a 100% Japanese motor. Maybe vibration is a too strong of a word. Some discribe it as "buzzy". You can feel it through the steering wheel and shifter. I kind of like buzzy - input is good when driving on the edge. I am trying RP because a rep dropped some off for me to test on the Shell 4 ball. It did very well, so I thought I would try it in the P5. I plan on doing an analysis at 5000 miles. I have always run Mobil 1 in the past and really like it too. I have 15w-50 in my '66 Datsun Roadster and change it once a year - only about 5000 miles, but very, very, very, hard miles YEE HAA [Burnout] vroomm vroomm rev rev

I just switched my ford 4.9 from dino 15w40 to Amsoil AME 15w40, and I can feel a difference. Is it a huge difference? No, but it does run smoother - I have even had passengers say so.

Possibly cases of "hypersensitivity" like when you change the oil and it seems to run smoother and better. Possible solutions: Double blind study or; Use of industrial vibration sensors that we use to determine when maintenance is going to be needed on electric motors etc.

Hey Roadster. I have a 2002 Protege LX sedan with the same 2L engine. After putting in M1 at the first oil change, I thought it felt just a bit smoother. I don't feel any vibrations, but I can't remember if I did before making the switch. [I dont know] I'm convinced that it makes a difference though, so I'll go with M1 again at it's next oil change. PS - the Protege sedans are just as fun to drive around the twisties [Big Grin]

Cool another Protege owner. Mazda did a great job on these cars. Consistantly rating #1 in the auto mag comparisons. Hey cjb200 isn't it cool when you hit a corner really hard and your wife's eyes about pop out, stuff slams the door panels at velocity, the tail end kicks out just right, blue lights in the mirror.... [Cool] Sorry for getting off topic guys.... But it is good to know the oil is keeping the motor happy at 6000 RPM.

[Off Topic!] but I disagree. I owned a '96 Protege with stock 185/65/14 tires and it wasn't comfortable at all... [Frown] Oz

I hate to stay off topic but... The 96 was a 2nd generation Protege, which was more of a typical economy car. The 3rd generation (99-03) are much better handling.

Heh, I know about 'buzziness'. Drive a Integra Type R at 8000+ rpms. No sound deadening is great. [HAIL 2 U!]
