has anyone used pennzoil or G.M Synchromesh in a kia or hyundai 5 speed manual. car has 30000 miles on factory fill of 75w85 oil cold shifting is no [censored] warm to hot is fine. I was just wondering if the pennzoil was a good choice to replace the factory fill with.
pennzoil syncromesh in a kia specd for 75w85

I dont think its rated for transaxle use. Find a good semi GL4/5 with soft metal protection. But you may end up just having to deal with the balkiness. How is the clutch engagment? - coming out high enough off the carpet? I have shifting probs but they are hydraulic clutch throwout related.
GL5 would be wrong??? I'm almost positive you would want a GL3/GL4
I have the BG 75w85 in my 6speed Aisin transmission and it works very well cold and hot.

clutch engagement is fine, i would guess at it starts to pick up at a few inches off the bottom .i don't know if this is relevant or not but if i slowly release the clutch in first without any throttle input i can start out without stalling.
Redline MT 90 is for you. Its GL4 75W90
Manual transmission fluid has nothing to do with the clutch. The clutch never touches the fluid, the fluid in your transmission has nothing to do with the fluid your clutch uses as hydraulic fluid.
How on earth would Synchromesh not be rated for transaxle use? That is exactly what it is for.
Personally, I wasn't that impressed with Synchromesh in my 02 Accord. And, it wasn't that cheap. IIRC it was about 7 bucks a quart, versus Redline or Amsoil which will be about 10 and probably offer better performance.

Of course P S is for transaxles!
Pennzoil Synchromesh is easy to obtain over the counter.
It is a dino fluid, and it is pretty good.
I'd consider a full synthetic like Redline or Amsoil , however.
Redline MTL or Amsoil MTF are synchromesh type fluids, and would seem to be what you are looking for for better cold shifting.
Redline MT90 and Amsoil MTG are also very good, but are somewhat thicker.

I was inferring that if the clutch was not fully disengaging you would have gear change issues. I mentioned this bc my Toyota has a mystery hydraulic clutch thet seems to self misadjust dowen to the carpet every other day. Penn Synchromesh GM/Chry is an app specific fluid and is not a universal transaxle fluid for GL4 applications. It is formulated from a thick 20w oil with vii. Worth as try I suppose - its just a KIA

I'd go 50:50 with Redline MTL:MT90, or Amsoil MTF:MTG
I would not go straight synchromesh, mtl, or mtf.
Kia/Hyundais originally required 90wt gear oils. They just recently started to use a 'lifetime 85wt' gear oil(same move that other automakers made, like Nissan....).
Its normal for the cold shift to require a little more effort.
The fact that Amsoil/Redline.... are full synthetics should ease some of the cold weather shift issue.
A mild increase in wear with a thinner fluid can shorten the life of the transmission. And, thinner fluids can make the gearbox noisier. Since you didn't list year/model/make/drivingstyle...... this is something you need to consider prior to going any thinner.
Btw, your northern climate, which is typically cooler, can get away with the thinner 80wt's. Or, you can blend thinner if 50:50 isn't good. Go 66-75% with the thinner oil.

its a 2008 rio5 which will see mostly city driving. And not be driven to hard. Like ARCO says its just a kia. LOL. What would make this oil a lifetime fill, i doubt that the factory fill is a high end oil, and good enough to last a lifetime.

I have calculated that 27% Redline MT90 and 73% MTL will give something with the same 40 and 100C. viscosities as Castrol Syntrans, an ideal 75W85 manual transmission fluid unavailable in the US. Just right for my trans in my climate.

The Nissan MTF is a 75W85 GL4. You could always give that a try. I couldn`t remember if Amsoil MTG was mentioned in this thread. That could be another option,but it`s a 75W90 and not a 75W85 (if it makes any difference).

I have the BG 75w85 in my 6speed Aisin transmission and it works very well cold and hot.
I also have used BG Synchroshift II (The fully synthetic one) and it is the finest manual transmission fluid I have ever used. I don't know what it is about it, but it just makes the shifter work like butter - cold and hot. It is GL4 rated.

I had a 2007 Kia rio 5, and its a much higher quality design and build than the Yaris I drive. Excellent handling chassis and well finsisehd interior. I liked the Yaris because the motor was a bit gutsier and the shifting quality was less 'girlie' for the lack of a better term. The Yaris was less expensive too. Are you running the 5w-20 oil in the engine? Mine spun a rod bearing day1.

the engine has been run on honda 5w20 from day one,seems to run well on this although i find the engine noisy on start up in both hot and cold weather, we have a 2006 spectra which has only used petro Canada 5w30 and runs much quieter on start up. As for the rio the only problem has been a front wheel bearing at around 34000 kilometers.
Going a bit lighter with a full synthetic lube should more than compensate for the heavier conventional that is in there.
First, the conventional will shear to a lighter viscosity anyway.
And in a trans, full synthetic will be better for wear.

Arco, why do you keep posting this stuff? Did you in fact tear the motor down and find a spun bearing on the 2nd day of ownership?

I agree. I was using Amsoil 75w90 Manual, and I did notice that even compared to the oem fluid, it was stiff when it was cold out. As far I know it "worked" ok other wise, but I put the BG Synchroshift II in it and it works very well, much smoother when cold, and always seems to shift fine. I don't notice any excess noise or anything like that in the summer either,

At around 9cst, the BG SynchroshiftII is very similar to Pennzoil Synchromesh fluid.
If you're not abusing the vehicle, if you plan on sticking with a reasonable(
And, "its just a Kia" isn't an argument to go thinner. Its a great car, you're paying for it, and you bought it.

the more i look at the numbers, i think undummy is right the pennzoil is to thin, i think the redline Mtl would be a better choice if i want to go thin. It rated as a 75w80 instead of 85 and is rated as a gl4. And the best bet would be a mix of Mtl and Mt-90. Or the amsoil versions in a mix.
