RE: 20w/50 or 15w/50
So you found that a thicker motor oil would not flow as fast,
and that newer motor are put together with tighter tolerance and the thicker oil
would not lube all of the motor parts and you would get premature wear.
My last two vehicles one used a 5w30 new and at 150K I was still using it, my truck had 220K
and stayed with 10w30 from day one.
My Disco I 10w40 summer 5w40 winter.
The only time you may want a thicker oil is when the motor has wear, not seals leaking
but metal ware.

10W/30 oe 190W/40 is as heavy as you need to go if you live in the hotter areas other wise a 5W/30 is great. Trick is get the best oil and filter you can buy and change the oil every 3000 miles.

Not really.. 10W30. I ran 10W40 this spring and had a lifter tick. I drained it and put the 30 back in. Sounds like new...

Had to edit and say the price is for motor oil, not gear oil, it's higher. If you want a quote, let me know..
