per0781 Posted October 5, 2003 Report Share Posted October 5, 2003 You went from regular oil to full synthetic in 1 oil change? When I changed from regular oil to synthetic, I did it one quart at a time. First oil change, 1 quart synthetic, 3.5 quarts regular. Second oil change, 2 quarts synthetic, 2.5 quarts regular, etc until I reached full (4.5 quarts) synthetic. Quote Link to comment Share on other sites More sharing options...

brian89gp Posted October 5, 2003 Report Share Posted October 5, 2003 I dont see whats so bad about regular oil After 3k miles mine was thick, pitch black, and had the consitancy of cottage cheese. I put Mobil 1 in and quit driving that way, go figure. Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted October 5, 2003 Report Share Posted October 5, 2003 I have never had problems with regular oil. I dont drive mine like a bat outta hell, but I do drive it hard. After 3K the oil is just fine Quote Link to comment Share on other sites More sharing options...
per0781 Posted October 5, 2003 Report Share Posted October 5, 2003 I noticed mine runs a little bit coller with synthetic too Quote Link to comment Share on other sites More sharing options...
91GranSport Posted October 7, 2003 Report Share Posted October 7, 2003 Yeah, you don't have slowly add synthetic oil to your regular conventional oil at every oil change until it's 100% synthetic. When I switcehd from conventional to synthetic on my old W-Body I did it in one shot and had no problems. If it leaks, it leaks. I went from regular to full synthetic in one oil change. no problems, in fact, my little oil leak is gone now. Quote Link to comment Share on other sites More sharing options...
91GranSport Posted October 7, 2003 Report Share Posted October 7, 2003 Nothing's wrong with conventional oil, it just doesn't offer the same amount of engine protection that synthetic would. As long as you change your oil and filter on a regular basis, you can run the cheapest, shittiest oil you can buy. I dont see whats so bad about regular oil Quote Link to comment Share on other sites More sharing options...

kiwi133 Posted October 7, 2003 Report Share Posted October 7, 2003 define shitty oil for me and tell me the difference between "good" oil and "bad" oil Shitty oil comes in plain looking containers. Good oil pays for advertising, bad oil doesn't. Quote Link to comment Share on other sites More sharing options...
SmoothSteve3 Posted October 8, 2003 Author Report Share Posted October 8, 2003 Now that I've had synthetic in my Lumina for a few days, I can already feel a difference! Everything runs soooo much smoother and it just plain old feels good. SmoothSteve Quote Link to comment Share on other sites More sharing options...
grandprix104 Posted October 8, 2003 Report Share Posted October 8, 2003 Texaco Havoline is suprisingly one of the best oils we sell at checker. The worst is Penzoil. Personally Valvoline Maxlife 5x30 is my oil of choice. It works REALLY well and helps quiet out my engine a bit. Valvoline makes one of the finest quality oils, penzoil actually has very high amounts of wax and varnish materials in thier oil. Synthetic is pretty much not worth the money in MOST cars. It will actually void your warranty if you use it too soon on some new cars. Some Manufacturers want you to hold off on synthetic until 60K miles, then some use it in the factory.

xxXRandyyXxx Posted October 8, 2003 Report Share Posted October 8, 2003 i use penzoil, i have never had any problems with it. so if it aint broken why fix it Quote Link to comment Share on other sites More sharing options...
grandprix104 Posted October 8, 2003 Report Share Posted October 8, 2003 because penzoil gums up the components in your engine and brakes things so you have to fix it. Ask any decent mechanic what they use in there car (thiers not thier wives ) and the will 9 times out of ten say valvoline (or some synthetic).

kiwi133 Posted October 8, 2003 Report Share Posted October 8, 2003 So if I use penzoil a few times it should clog my leak? Hmmm, actually, thats just about crazy enough to work. Quote Link to comment Share on other sites More sharing options...

brian89gp Posted October 9, 2003 Report Share Posted October 9, 2003 I'll take your word for it, but my family has been using it forever and had 0 problems with it. My family has been using the cheap walmart brand for ages. Got 260k out of a Ford 3.0, 220k and counting on a Chevy 3.1 Iron head, and 110k and counting out of a 3100.

grandprix104 Posted October 10, 2003 Report Share Posted October 10, 2003 i never said it didnt work (Its oil! - as long as you have something in there youre fine) but its just not the best - especially since valve costs the same... but to each thier own thats just my own experience and what i hear from mechanics and such...

john99gtp Posted October 10, 2003 Report Share Posted October 10, 2003 Can someone please list the pros and cons of synthetic. I was thinking about buying some at work last night, but i wasnt sure. What are the MAJOR pros of synthetic, as well as cons. Do i need to be careful when changing to synthetic? or should i just go full blown. Lemme know John Quote Link to comment Share on other sites More sharing options...
Whiskey River Posted October 10, 2003 Report Share Posted October 10, 2003 What are the MAJOR pros of synthetic, as well as cons. Do i need to be careful when changing to synthetic? or should i just go full blown. Lemme know John My Lumina has used synthetic in it for the vast majority of it's life, it has 178k on it and up until the modulator decided that trans fluid was good for the intake, it idled smooth. About the only con to synthetic is when you only commute a couple of miles and don't give the engine a chance to remove all the condensation. Dino oils have polymers that help with this, but if your commute is more than a few miles, then synthetic is a better choice. As for the change, dump the dino and fill it up with synthetic. No need to blend them together in the transition. Quote Link to comment Share on other sites More sharing options...
grandprix104 Posted October 10, 2003 Report Share Posted October 10, 2003 Pros of sythetic Doesnt break down as quickly 3000+ miles Less wear on your engine Very good for racing! Cons of synthetic EXPENSIVE!! $3-4 a quart compared to $1-2 Can Cause leaks in otherwise sealed engine Can void warranty by preventing normal break-in period from bieng accomplished thus causing shorter engine lifespan. Check the manufacturers specifications on break-in period before using it it varys GREATLY If you have the money and your car can take it use it if not youre really not missing THAT much.
