Mobil 1 Mobilube PTX 75W-90 SKU: 00004320420L

For my 2003 996 with 75k miles I updated to the 997 shifter console which gave a slightly shorter more precise throw and then after a few weeks changed to Mobil PTV 75W-90. The change in lube made as big an improvement in feel as the console change except the change was to the smoothness of the shifter movement. Now the car really shifts the way I want. Amazing was less than 3 liters of a different lube can make. Strongly recommended.

I have a 07 carrera that was hard to shift when cold. I tried several other sythetic 75w90 oils and all were the same. my tech told me to try the factory PTX and it was amazing. Cold crunch when shifting is gone, smother all around. with I had done it years ago. well worth the extra cost to get it right.

I bought 3 liters for my 2008 C4 manual to do general maintenance at 40k miles. Easy DIY task.

2009 C2S 86K miles manual. I had the classic jamming going into 1st. This fixed it. My manual denotes changing this at 120K miles.... BS.... it should be changed earlier. I don't know why or what was wrong, but changing this out for what is recommended in my manual cures this ill.
