Hello guys I have Seat Leon 2008 TDI BMN engine 220.000km, K&N Panel filter, downpipe 76mm and complete straight pipe 63mm. I got my turbo 1749vc to hybrid 1752, What type of oil should I use the car was running on 5-30w but the tuner told me for that kind of turbine that I need to run on 5-50 or even 10-60. Thoughts on this ?
