Hi there,
I have a wrx 300 and always start it up for a few moments before I drive, always take it under 3000 revs for the first 10 mins etc etc.
However I want to know the pros way of telling when it is warmed up via a oil gauge temp pod. Can you please let me know who much I should expect to pay and what would you recommed for me to get as a newbie. Don't want 3 pods only the most essential one please.
Thanks in advance.
Martin
