I changed oil to Pennzoil synthetic today. I "feel" a difference

I get no warm and fuzzies from my Mobil 1, and I KNOW my power band is working...I cleaned and oiled it just last week.

 

You're right on, IMO. I couldn't agree more. While those of us who have refi'd in recent years (I'm at 5.5% 30yr fixed) have made out well in that regard, the anemic value of the dollar is killing us. The only good thing that can be said about it is that more tourists from overseas will come here because their money is worth more. That's about it. The bottom line is, interest rates HAVE to go up to help control inflation. There's no question about it.

 

Well, back on topic:

-Switching to a synthetic oil during any time in your truck's life should not cause a problem. Note that the engine might have more oil leak problems since synthetic is more viscous and conventional oils help goop up the holes.
-They don't advertise MPG gains because it's not an easily measurable benefit, I assume. Results may vary!
-Running Amsoil in my old Accord for oil and transmission, I can notice a definite increase in smoothness.
-My dad's Camry runs with amsoil and a bypass filtration system. At a 12k oil change, his oil looks the same as when he put it in; when he takes the oil to be tested they state he's good for several thousand more miles if he wanted.
-you should notice a definite decrease in engine temperature. Using both Amsoil oil and transmission fluid, we saw as much as a 10 degree drop in temp on our '99 Dodge Diesel


BTW, I'm not trying to necessarily plug Amsoil, that's just what we use. Try bobistheoilguy.com to get better answers and more alternatives.

 

You think so, huh: http://www.toyotanation.com/forum/showthread.php?t=258260

 

The person in your article could very easily be suffering external issues he is unaware of, doesn't state modifications, and doesn't note his driving habits. If it's truly the fault of the oil, Amsoil will cover the cost of the entire engine repair. Last I heard, there hasn't been any cases filed.


I can just as easily say:

-look here: http://www.amsoil.com/testimonials/409000.aspx
-Take your complaint to bobistheoilguy.com, it's a forum that ONLY discusses fluid and contains folks OBSESSED with oil.


I made a mistake, I talked with Dad today, and he is having analysis at every 10,000 by an independent lab and changing every 36,000. The Camry is sitting on 465,000 miles with a daily commute of 120 miles.

...and furthermore, I'm not making Amsoil to be the ONLY choice in synthetics - only that I expect other synthetics should be performing BETTER than conventional.

 

I know quite well what BITOG is, thanks. Years ago, BITOG got me started on testing so I'm quite familiar with the ins and outs. IMO, the extended oil drains that Amsoil recommends are ridiculous and make your engine a ticking time bomb.

Posting testimonials from an Amsoil site doesn't prove anything. They are in the business of making money (nothing at all wrong with that) and will report what makes them look best. Nah, no bias there.

BTW, that is not an "article". That is a thread on another forum that was started just last night. We'll see where his issue pans out but I'd really like to know how sludge, if in fact that's what the issue is, would be created "externally". Interesting concept.

 

I started writing a ton, and hopefully I've cut down the rambling:

Would you concede that Dad's oil analysis from an independent (read: NOTHING to do with amsoil) lab at least makes a favorable point? I can see about posting the results... Fact of the matter is, I have 2 vehicles that are driving around on a daily basis that have both been subjected to the extended drain intervals through the life of the vehicle, and aren't showing signs where we need to change habits.

Anyone out there with some good comparison tests between oils with measurable data? I'd rather talk about something showing royal purple, mobil, red line, castrol gtx, etc., stacked against each other. Who knows, maybe the Wal-Mart stuff comes out in spades?

-If possible WilsonTD, I would highly recommend referring the OP to the warranty claim information, regardless of our conversation here. If he's able to make a claim in his favor, it's not going to hurt my feelings (maybe the company is taking a dive, maybe the customer got a bad batch), I'd rather see the guy get a free engine.

-Moving beyond the drain interval discussion, getting back on track, I think we can at least come to the conclusion that given an equal oil change interval, a synthetic will add performance benefits, both measurable and immeasurable, over conventional oils.

Sorry wrong choice of words. Don't get worked up, I'm on my second round of 13 hours doing this -> as I pile drive studying a MS certification. So far have been doing quite well in the coherency department I think! If I'm coarse on something, take it in stride until the weekend when I can think again.

I don't know the specifics of the guy who's engine sludged up after several 25K oil changes, nor have I read much of Amsoil's footnotes and other warnings, but most all oil manufacturers/marketers state that oil analysis and in some cases a bypass system should be used before attempting such long service intervals, and long trips help, since short trips cause condensation that the bypass filter will not take care of. Some with proper techniques can do long intervals, but the poster who is complaining on the other post appears to have just decided to run a premium syn and just change it 4 times in 100K, which is not the way to do it, so I doudt Amsoil will handle any warranty claims........

 

I have been waiting to do this forever! I just can seem to find the right oil for MY power band any suggestions?

 

Sorry,never
