schmidty77 Posted March 31, 2003 Report Share Posted March 31, 2003 I was wondering what everyone's opinion on oil types to use. I have bought into the synthetic thing for the past six years. I first used it on a 97' Dodge Dakota for the three years I had it and then in my 00' Chevy Silverado with 5.3 Vortec. Since I've never owned a vehicle much longer then three years straight, What oil is better performing and better for engine life. The only thing that I really noticed was that synthetic doesn't burn off quite as fast which may or may not be a good/bad thing. What's everyone elses opinion.

RATFINK Posted March 31, 2003 Report Share Posted March 31, 2003 For the purposes of lubrication almost any oil is as good as you maintain it. Nothing wrong with synthetics, but I never run them. I run good old fashioned dino oil, and I have put over 200k miles on pretty much every vehicle I have owned since the late 80's with no problems whatsoever. The main thing is keeping the oil changed on a regular basis. RF Link to comment Share on other sites More sharing options...
bohicatmc Posted April 1, 2003 Report Share Posted April 1, 2003 I have used mobil 1 in everything that I have owned for the past 20+ years...great stuff...but Ratfink is correct ..any oil is good as long as it is maintained right. Link to comment Share on other sites More sharing options...
C5SilverBullet Posted April 4, 2003 Report Share Posted April 4, 2003 After your break in period I would switch to Mobil 1. I run it in the vette, and while I have no written proof or anything I prefer it. Link to comment Share on other sites More sharing options...
SSS Posted April 19, 2003 Report Share Posted April 19, 2003 The great enemy of oil (and everything else) is heat. Synthetic oils tolerate heat better than organic oils. Actually, it is the additives in the organic that break down first. If you create a lot of heat from your driving, i.e., heavy towing, very aggressive driving, hard racing, etc., then synthetic may be the way to go. Note that some manufacturers are quietly agreeing that users of synthetic oil can extend oil changes to 5,000 miles. Link to comment Share on other sites More sharing options...
SSilverado60 Posted April 20, 2003 Report Share Posted April 20, 2003 My 2000 ran much quieter after I switched to synthetic. No more piston slap. It quieted everything down. as soon as i get about 6k on the SS im gonna switch Link to comment Share on other sites More sharing options...

jwest1975 Posted April 20, 2003 Report Share Posted April 20, 2003 I switched over to Mobil 1 oil and filter at about 1400 miles on the truck. Justin Link to comment Share on other sites More sharing options...

Bombtech Posted April 20, 2003 Report Share Posted April 20, 2003 Mobil 1 is good, I used it for about 25k miles on my R/T and then switched to Royal Purple just to try it. I really didn't think I would notice to much, but I did notice a big difference in the smoothness of the engine as it gained rpms and it ran a bit cooler. You can get Royal Purple from Jeggs for about $4 and change a quart. I am thinking of trying red line, heard good things about them. Link to comment Share on other sites More sharing options...
schmidty77 Posted April 20, 2003 Author Report Share Posted April 20, 2003 I run Castrol Syntec only because when I tried it the first time I watched them pull the drain plug on the next visit. the used oil appeared to be fairly clean for having 3000 miles on it. Unlike the gloppy mud looking mess that oozed out of my other vehicles when my parents had me taking my Isuzu rodeo to Q-Lube. (Back in high school.) I'll have to look in to the mobil-1.

chevelleguy Posted April 20, 2003 Report Share Posted April 20, 2003 Any synthetic should out perform conventional in terms of oil life, since the carbon chains in conventionals break down relatively easy under heat and pressure (thus all the build up you see after 3k miles). In my Chevelle I run Mobil1 for 6k miles. After 3 changes, I've yet to drain more than slightly discolored oil from the pan. For slightly less agressive driving styles, oil changes between 9-12k miles are reasonable. For whatever it's worth, I used to work for Mobil in research and have been part of some of the case studies we perform accross the industry. Call me biased, but after seeing test results that aren't published to the general public, I'd never run anthing other than Mobil1. Link to comment Share on other sites More sharing options...

Did you also use the Mobil 1 Filter or another brand? I am considering Mobil 1 at the first oil change or sooner Link to comment Share on other sites More sharing options...
