I have to admit that before the LT I had ONE simple philosophy on oil, buy cheap and change often. I would buy the Wally world brand for 78 cents a quart and put in my truck. I ran it 3500 to 4000 miles, and changed religiously. I did that on all three of my trucks and every one of them were running fine, and no engine leaks or probs well over 100K on all and one was nearly 200k.
Enter the LT. I ran Mobil 1 15/50 synthetic to about 4K and got scared. I would change it. I read plenty about what 'others' were doing, but I couldn't bring myself to do it.
Then something snapped (or likely the price of gas and oil really sank in). I NEVER really concerned myself with the environment becuause one of my buddies burns the stuff to heat his auto shop. He had to pass EPA inspection to get licensed for the waste oil and burning it.
I'll cut to the chase. Now I STILL run Mobil 1 Synthetic 15/50. I'll run it to around 6K but NEVER over. I change ALL of my oils tranny, engine, and final all at the same interval.
Thus far, I haven't had any problems EXCEPT a failed rear bearing. I made one mistake, I changed my own rule. I have always used Mobil oils all the way around in the bike. This particular trip, O'Rielly's was out, so I bought Lucas for the final drive. After all it says is meets or exceeds any 90 weight.
400 miles later she was sitting in the repair bay getting the final drive bearing replaced. The mechanic says that there's no way to prove it was the Lucas, but I KNOW. I changed my pattern, and it bit me in the but and wallet.
Get a rhythm and stick with it!
That's all I got to say about that!
