Synthetic oil -vs- petrol oil

[cindih]

My husband wants to change my petroleum based oil to synthetic oil. I think its ok for his rice burners, but it kind of goes against my grain in 2500HD. Anyone out there with experience in this area?

The bottom line is that the synthetic oils are better than regular "dino" oils. From what I have seen using synthetics when I tore down a Supercharged motor that had over 114,000 miles on it and 90,000+ was with the blower on it, was that the oil worked great. The two oils I used was Mobil 1 or Castrol and even with #1 ringlands that had cracked the motor did NOT have to be bored one bit. I could still still the factory hash marks in all the bores and when we checked all the bores were within factory new specs. This was on my Supercharged 1995 z28 Camaro. The reason the motor ringlands cracked was that the FMU that came with the SC kit went bad. Just my two cents. Good luck.

No worries going to synthetic. It will be better for your HD motor, espectially if you live in a hot or cold climate or tow or haul.

Thank you also, makes me feel some better. Ive had GM trucks for alot of years with no probs. Las Vegas gets REALLy hot so I wanted to do this change before summer hits.

I use Mobil 1 in two of my four vehicles. My Corvette and Acura RDX (Turbo) both came from the factory with Mobil 1. I don’t think 2 major automakers would recommend synthetic unless it was worth it. They would save $$ if they didn’t believe it was important. I also ran mobil 1 in my Tahoe until I sold it to improve gas mileage and durability. My .02

Glad I could help. Another good thing with the synthetic is that I don't worry about the heat or cold effecting the oil as much, and I know it is safe to go to 4000-5000 miles before a oil change. Also since you live in Vegas you know how hot it could be. I was stationed out at FT Irwin with is by Barstow CA. Well long story short since FT Irwin is basically below Death Valley, it maybe the one place that gets a little hotter than Vegas, and I had no issues with running a synthetic in my 2500 Suburban and my Camaro when I was stationed there. I hope this helps, take care and don't have too much fun in SIN CITY!

I have not myself "yet" but I have had 3 people tell me that royal purple and I hope I got the name correct is supposed to be very good and you can change from regular oil to this stuff and not have to worry about cleaning the old oil out and by the second oil change it is all synth. oil.

 

They were also saying it does not break down as fast as regular oil but it is a little more expensive than most synth. oil and holds up better in heat and cold than regular oil.

 

Hope this helps

Agree, especially in the heat of LV. A friend of mine moved out there four years ago and when he switched his Harley over to synthetic his oil temperature on his Harley droped 8 degrees. The beauty of running a synthetic, holds up to the extreme heat as well as helps cool better than regular oil, it also makes for easyer starting in the extreme cold and faster oil flow to the top half of the engine.
