synethic oil blend?

[beamer]

I went to get my oil changed today, actually then had to make a appt for tomorrow, so quick info needed. its at firestone. they have a coupon for a synethic oil change. $ 20.99 which is pretty cheap. I know, you pay for what you get. anyways - the $ 20.99 special is kendal 60% synethic blend - 60% synethic 40 % parrafin. Is this good for my 96 LT 1. I can get the oil change for $35.99 and it will be the total synethic.
Appreciate any info.

Do you buy mid-grade 89 octane when it's cheaper?:nono

Spend the $35.99:bang
You don't even have 25K on the car yet. I'd stay with the same oil that's been used in the car. MOBIL 1 perhaps?
If you can't do it yourself then find someone that will use your own oil.

syn oil

no - I don't. I buy 93 octane. I'm not a idiot who abuses his corvette. The last oil change was $ 60.00. And hey whats wrong with saving a couple of dollars if it is valid. Not every vette owner is a aging baby boomer with more money than brains. I wanted to know what the difference between the twq were and any affects. Both cans of oil had the sunburst symbol on them.

I don't know anything about your 96 engine and would not to pretend to. But my L 98 is just a chev 350 ( and a very bad one too) chev made a lot nicer 350"s than this. But they say mobile 1. not in this engine! i can rebuild it cheaper than doing 10 oil changes. But syn. oil has many benifits none of witch my eng. need. Your eng. might need the syn. oil IE; valve train, seal compisition oil pump,ect, Lots of new eng. do. However no engine can be broken in on syn. oil it won't let the rings seat. It's just too good. A 96 and not knowing any more than i do i'd go with the owners man.til i knew better.

The factory fill was Mobil-1 in all LT-1 motors begining in 92. A full synthetic was used because of the higher heat encountered after GM decided to no longer use the oil cooler found in the L98 motors. Mobil-1 or an oil meeting GM4718 specifications.

Last year, I found some Pennzoil Full Synthetic oil that had a blurb on the label that said it met GM4718. When I went shopping for Mobil-1 this week, I noticed that the Pennzoil Synthetic bottle had a new design and the reference to GM4718 was gone. Quaker State has a full synthetic that says on its label that it meets the GM spec.

I would not use any other oil that Mobil-1 in my 92. Have you asked the folks at the Firestone store if you could bring in your own oil and have them just do the filter change and lube?? While I usually do my own oil changes, I have taken my Vette to the local Chevy dealer and they have no problem with a customer bringing their own oil.

You can find Mobil-1 on sale every so often at Wal-Mart in the 5-quart jugs for around $17-18. Costco has a 6-pack case for $24.

I doubt that 60% synthetic blend will adversely affect your engine at all unless you drive the snot out of it. Somewhere on this site is an article by a GM vette engineer (I think). He was explaining why GM went with Mobile 1. He did mention something about the Mobile 1 compensating for the lack of an oil cooler (cost savings for GM). Also he indicated that GM got one heck of a deal on bulk oil due to the big Mobile 1 advertisement under the hood!

His entire article led me to believe that standard petroleum based oil, changed every 3k mi. or so would meet non-hotrod use in our vettes. Actually I'm coming up on an oil change and am very seriously thinking of running 10w-40 for the summer months here in Ohio.

Spend your money as you like, but educate yourself. Advertising and hype has a major impact on sales of anything.

Personally, if I used my vette for racing I'd definitely stick with the Mobile 1. Also, when I fly you can bet there's 100% synthetic in the aircraft engine also (mucho heat!).

If I misinterpreted the article, would someone please set me straight.

THAT'S LIKE BRINGING YOUR OWN EGGS TO BREAKFAST!

Check to see if the oil meets the GM4718 spec... if not pass it up. The 92 - 96 Corvettes have no engine oil cooler, the oil gets very hot, especially if running at high (>=2000) RPM. It's not unusual to see oil temps of 212 - 220 on a hot day.
The synthetic oils have the ability to withstand much higher temps and maintain their lubrication properties over conventional and/or synthetic blend oils. It's worth the extra cost in the long run. If you're on a budget, although it may be tempting to save $$ now on oil, just think of what would have to be shelled out to pull, dismantle, and replace parts that were damaged because of less expensive oil that couldn't protect the engine.
Remember that old Fram ad... "we can get a little now, or a lot later"...

Some Corvette LT1s do not have a engine oil cooler .
Since this may cause the Vette LT1 to run somewhat hotter, synthetic oil is used for it's ability to withstand higher temperatures without thermal/ viscosity breakdown. Although, Corvettes with the performance suspension are supposed to have oil coolers.
Synthetic oils flow freer during cold weather and cold starts
Synthetic oils take longer to break down
Synthetic oils adhere to engine parts better

Ok here goes from 1975-1981 I helped develop the x-m1 main battle tank now known as abrams m-1 we had an avco lycoming agt 1500 turbin eng. in it this is basicly ajet eng. but it turns pounds of thrust into mech. power through what is called a recouperator. The eng. spins @ 100.000 rpm. we had to use this special oil from "mobil" it was a syn. oil. and came in the typ.od green can. So us big shoots working on this top secret project thought that if this oil was so good for the agt 1500 we'd put it our cars.( at the gov. expence) ooooooops! after several of our cars burnt motors coming from or going to white sands missel range NM.( Or saw bad oil leaks) Someone looked at the wrighting on the can. "DO NOT USE IN INTERNAL COMBUSTION ENG." to this day I don't know exactly why this pure syn, oil wont work in a slow swinging eng. and I couldn't ask them.(we stoll it) but i do know 100% syn.

Good job on the tank. I'm a tanker.....Do you recommend syth for my setup? BB 402?

It is recommended for a reason. Not worth the risk. You sound like a caring owner of a really nice car why cut corners here.

synethic oils

thanks for all the info. I appreciate it. I didn't mean to get anybody riled. i try to take great care of my vette. I just spent $1400 on 4 new tires, 4 wheel alignment . The oil change was $60 and I'm not able to do it myself. So hey why pay more if you don't have to. But I would not go cheap if it would affect my car. I had never known that there were synethic blends. Yes - I've only used mobil 1 .
thanks

 

[FordNoMore!]

Use Mobil 1, end of story.
