I have a '96 Mazda Miata with the 1.8L DOHC I-4 which is quite famous for HLA noise upon cold start-up. I was using Mobil 1 5W-30 and 10W-30 when I first got the car. I decided to try German Castrol and its been in for about 1,000 miles now.
With the Mobil 1, I'd get HLA noise when the oil had been in for 4,000 miles. I took this as a sign as to when the change the oil. It would also turn black. I know visual cues aren't the best, I'm just a bit paranoid. The GC has already started with the HLA noise.
Would the 0W cause greater HLA leak down and more HLA noise? It usually happens when the car has been sitting for 8-10 hours and during colder weather.
