Synth transm oil or tires?

[Yezinki]

I have noticed that when I release the clutch in gear 1at 5K plus rpm the tires spin for a few moments before the gear gets engaged & the car starts to move.
Is it because I switched from the dealership mineral based oil to fully synthetic 75W-85 manual transmission oil, the car has done only 13K miles.
Never happened with the mineral based dealership one……or will the gear box take some time to get used to the synthetic one or it’s not the oil it’s the tires not having a good wet/dry grip??

Is this a serious question?

That would be the tires.

What tires do you have? And in what conditions were you driving in? Your tires probably don't have enough grip for them to spin. It is kind of confusing the way you phrased it above. Your gear is already engaged when you released clutch.

75W85 sounds like a gear oil btw. Unless you are building the car for racing, sticking with OEM fluids is usually the best route to go. Plus putting in a fluid that is not recommended for your vehicle can void any warranty(ies) you may have from the factory/dealership.

Agreed the gear is already engaged……Yokohama tires…….yes 75W85 is synthetic gear oil as I wrote earlier………previously had the original Toyota manual transmission oil which is mineral based & was dirty at 13K …….this was the first change of the transmission oil…..I feel the tires too………happens both in dry & wet conditions…..which tires in your opinion have the best dry & wet grips.

I have

They are amazing in dry conditions, and great in wet/light snow. On heavy snow, they are still pretty good.

If your looking for new tires, it depends on what you want/need. On my summer tires I just picked up, i have

You can tell just by tread that they will be better gripping on dry, but may not be as good in wet, and horrible in snow.

The change from mineral to syn. oil has little to do with the tires spinning when you drop the clutch at 5K.

I would expect the tires to spin dropping the clutch ab 5000 rpm. Why such a lead foot? You will be buying lots of tires, and replacing clutches much more often if you drive that way all the time. I will say that my 05 came with Goodyear Integrity tires, and if it is a bit wet, they will spin a little even with a gentle take-off. I have two corollas, and on one the tires were already replaced with cooper tires, which i like, good all around tire. The other one will have the integrity tires till i wear them out, I am cheap that way.

+1 on the 5k RPM "spirited" driving

This generation of Corollas also have a problem with their manual transmission... most have popped at 80000 miles and Toyota have yet to remedy the problem.

I know the liquid seems dirty at 13k, but you throw new motor oil into the engine bay and do an oil change later its still going to come out looking a bit darker then when you put it in. Your transmission coming out dirty just means that the oil is removing the waste, doesn't mean its a bad transmission oil. OEM fluids have the right viscosity and chemical additives for your car, can't go wrong if they came out the factory with the fluids right?

Unlike previous generations of Corolla, this generation of Corolla was made to be an economical, family-oriented sedan... Go easy on the clutch... and like Steve said, your tires, clutch, and transmission will last longer.

Toyota recommended transmission oil change at 13K?
I agree the oil will look dirty……but it had lots of dirt/sediment when drained in the bay?
What are the few best possible new tires for dry & wet ……..no snow in Hawaii.

Thanks.

I replaced my gearbox oil at 15k with synthetic. Mine was as clean and clear as the new stuff I was putting in.

Gearboxes are sealed units and the temperatures stay pretty low. You shouldn't have any contaminants in it when replaced, other than a shaving or two. A bit of darkening with age can be expected, but it shouldn't be anywhere near the color of motor oil.
