My brother-in-law saw his first SSR, mine, last weekend and suggested I switch from regular oil to synthetic oil in my SSR as it would last longer and give me better gas milage. Is this true, and is it safe to go from regular 5W-30 pennzoil to 5W-30 Mobil 1 Synthetic oil? Is the 5.3 designed for synthetic oil? Would I have to flush the system before installing synthetic oil? How do you know when it's dirty, and how often do you have to change synthetic oil?

Not on the 5.3s. No problem to just change to synthetic at any time. I did mine after 500 miles, and still change oil every 3000 to 3500 miles.

My dealer told me to go two oil changes to let things seat in. Then I could go to Mobil 1. I have the 04. On the 05 they start out with Moble 1.

I have run Castrol Syntec in all my cars for the last 10 years. Mobil 1 is also good, but I find I lose about 3/4 of a quart between oil changes using Mobil 1.

You will find improved oil pressure even on hot days and will find the oil holds it lubrication properties longer.

I would say on average I get about 1 or 2 more miles per gallon using syn. oil! Every mile per gallon counts with today's gas prices!!!

Mobil !

My 05 came from the factory with Mobil 1 in it. It even has a Mobil 1 sticker on the oil fill cap. Chevy suggest oil change every 4000 miles, Mobil 1 suggest every 5000 miles. The switch can be made any time after the proper break in time. There are many good synthetic oils on the market. Do some research and make your personal choice.

Okay ive been a Mobil ONE fan for many years running it in my Z06's and my 95 Impala SS.. so please tell me what weight oil you run on the Royal Purple?
I run 5W30 Mobil One here in Texas.. what weight should i run with the Royal Purple, and do you lose any oil or is it low between oil changes with Royal Purple?


I would like to run the Royal Purple after i get my SSR... check it out for a change.
I think the only thing ive seen with Mobil One is you lose some between oil changes because i was told it will find its way out of an engine.

thanks Tony

Royal Purple

Z16Z06,

I too have used Mobile 1 for a period of time and Just through word of mouth and performance comparisons found that mobile is towards the bottom.the best oil iv'e used is Amsoil but you can only buy that through private distributors and it proved to be a pain.
I now use Royal Purple 5w-30.I just finished a 2700 mile trip to Florida and back in my 03 Silverado and she is just as clean as a whistle,no consumption and 10-15 lb.higher pressure.

Thankyou 53wanab this is GREAT information and i plan on running Royal Purple in the SSR when i get it. Im currently working a deal out of Houston with a dealership with a choice of the 04 Ultra Violet, Black or Silver. i believe im going with Ultra Violet.. wanted Redline but i do like the U. V. color. too.

Thanks for the weight of 5W-30 Royal Purple.. Now is it really Purple? it would match my SSR.. LOL.. cant wait to get "her"

For more info then you can possibly digest in a month on oils, coolants, filters (oil and air), additives and gasoline - try this site : www.bobistheoilguy.com
Click on the FORUMS tab about half way down the page on the left side. After a year and a half of active "lurking" I have learned the following:

1) Use synthetic oil, change it at Manufacturer's recommended intervals.
2) The differences between synthetic oils are so minute it comes down to personal preferences.
3) Don't use "Dex-cool" in a vehicle not designed for it and equipped with it from the factory.
4) The BEST air filter is: (You will have to read the "ISO 5011 Air Filter Test" results yourself - you won't believe me!)
5) The WORST air filter is: (You will have to read the "ISO 5011 Air Filter Test" results yourself - you won't believe me again!)

These guys on the forums are FANATICAL about this stuff (hmmmm. . . sound familiar?), but it is worth checking out. As with most forums, you will quickly pick out the actual experts on the subject at hand and those that just like to type.

Happy reading!

Yea Z16, It is actually purple.I forgot to mention that one of the other reasons I like this oil is that it has very good heat transfer caracteristics and low friction. My engine so far seems to run about 10 degrees cooler.

I think this is my first post here... so hi! :cheers

I am a forum vendor for Troy on two of his other forums as an Independent AMSOIL Dealer and will be one here to if he gets to that point.

I appreciate the positive comment about AMSOIL. I've had the same results. Been using AMSOIL Series 2000 in my Corvette Z06 engine that sees exclusive track use, along with AMSOIL ATF in the tranny and AMSOIL Severe Gear Extreme Pressure gear lube in the diff. I've been extremely happy with the performance.

I'd like to let everyone know that getting AMSOIL these days is not that hard. One phone call or a few clicks to their online store and it will show up at your door in about 3 days. Cost is comparible to Mobil 1 depending on the product. AMSOIL makes three lines, XL-7500 a Group III synthetic rated for 7500 miles or six months, the SAE line rated for 25k miles or 12 months (similar to the new Mobil 1 Extended Performance) or the Series 2000/3000 line for racing and diesels.

There is info on how to order on these pages of my dealer website:
Request a Free AMSOIL Catalog
AMSOIL Ordering Information
AMSOIL Preferred Customer Program

If you want more info on the Preferred Customer program, feel free to email me at [email protected]

For the original poster, as mentioned above, a synthetic will work very well in your motor. I run the AMSOIL XL-7500 in my wife's Chevy Trailblazer which has the 5.3L V8 in it.

What does synthetic cost a quart? :flag
Mike,
I can't quote AMSOIL prices online, but they are very comparible to Mobil 1. Mobil 1 is normally around $5 per quart, maybe a little less at walmart. The new Mobil 1 Extended Performance oil which is rated to 15k miles is supposed to retail at about $5.75-5.95 or so, but I have seen it for about $5.36 at my local walmart.

If you want specific AMSOIL retail or preferred customer prices, I can share them privately via email or PM. :cheers
