I have a 2002 Jeep GC 4.7L V8 with 148,000 miles. I changed the oil every 3000 when using dino oil and 5000 if I am using synthetic oil. I do tow a boat on the weekends. I am adding about 2 quarts of oil in between 3000 oil changes. 5w-30.
The PCV has been changed, the compression is good, no...

I was reading on some forums that using a larger oil filter (If it fits) is a good thing to do. The pros are more filtration, more oil capacity. Is this true?
What are the con's?

Actually I just...

2002 Jeep Grand Cherokee 4.7 L with 146k miles. I am using the recommended 5w-30 oil. I have to add about 2 qts of oil during my 3000 mile oil changes. I changed the PCV. There are no leaks. The engine runs very smoothy. I do tow a boat with it. What can I do to reduce the oil consumption...

80-100 A year. What about using synthetic in the lower unit?
I am presently using 10w-30 Yamalube in my outboard. I am considering switching to Royal Purple 10w-30 and 75W-90 Royal Purple for the Lower Unit. My goal is to increase the HP a little while reducing wear and tear on the engine. I am to follow the manual and change the oil each season or after...
I have a 1978 35hp Johnson Outboard, that just came back from being serviced.
What 2 cycle oil should I use? (TD30?TD50?TCW3?,etc)
What grade gas?
Thanks,

My error it is 5w-30.
I checked the oil with about 2500 miles on that batch, and it is very clean as well as the filler cap. No goo or anything like that.

I believed the dealer used Kendal Syn blend 5w-20. On the oil fill cap it also says Kendal Syn Blend.

The engine is a V8 4.7. Runs well, no burning oil. The oil was changed every 3k by the original owner. I was lucky enough to get all the service records from the dealer.

I bought a used Jeep GC, it now has a 117k miles. I am going to start running syn oil through it. I am undecided as what oil to use. I am thinking of using royal purple or Mobil 1. Any thoughts?
