Switching To Synthetic

[97loudcut]

I am going to change my oil soon and I am debating whether or not to switch to synthetic. I was thinking about running Royal Purple 5w30 with some Lucas Oil Treatment. My engine has 114K and I just want to know if this is safe?

 

Please hold back on the "It's just a 3100 go buy some 50 cent oil" I really don't want to hear it.

[Psych0matt]

couldn't hurt, but I don't think you'll get any benifit from it

[SigEpCutlass]

Don't let people bother you with that fucking shit. I have a 3100, and it's been running Amsoil Series 2000 0W-30. It's been proven to be better than Mobil 1 Synthetic in tests. Most people buy Mobil instead of Amsoil, because of how much cheaper it is. Don't bother paying even more for Royal Purple, when you get better protection and equivalent performance from Amsoil.

 

Amsoil products have proven their worth in every vehicle my family has owned in the last 10 years. I got better gas mileage once I switches to synthetic in the cutty, and it's been on Synthetic for almost 35,000 miles. I'm approaching 100,000 miles very soon, and I don't have any leaks (except for the valve cover gaskets I've been too lazy to replace until it gets warm out). The valve cover is leaking ofcourse because of that crappy plastic cover my engine has...gotta replace that thing.

 

 

So in conclusion:

 

1. Fuck that 3100 sucks blah blah blah bullshit it's your car.

2. It makes a positive difference in my acceleration and fuel mileage.

3. You will have no problems leaving the oil in for longer service intervals as long and you're sure your intake gaskets are in good condition.

4. Forget about Royal Purple...it's not worth the money. Get Mobil 1 or Amsoil Synthetic.[br]Posted on: March 23, 2006, 03:34:18 PM_________________________________________________btw here's a link to what I use.

My dad also runs the same oil in:

'92 MTX Ford Taurus SHO

'00 MTX Subie Outback

'00 MTX VW Golf GLS

 

Several years ago we used an older version of this synthetic in a Honda Accord, and an Isuzu Trooper, both with positive results too.

i even use synthetic on my 3.1L MPFI!!javascript

You can use whatever oil you choose, I would suggest against using the Lucas Oil Treatment if you don't have any oil leaking or consumption problems. Lucas has lots of Esters in it and it causes rubber seals to swell. If they swell too much, they will harden and crack. Been there, done that.

[SigEpCutlass]

I missed that in the original post. If you use Mobil 1 or Amsoil Synthetic, do not add any additives like lucas to your oil. They already have additives in them to perform similar jobs.

[5speedz34]

I pay about a $1 more for Amsoil. Some people use Mobil 1 since it's easier to get a hold of.

[Prospeeder]

I wouldnt waste money on royal purple, but Vavoline and Mobile 1 are great quality oils, i Use Vavoline Synthetic in my car, and you dont have to change oil till like, 5-7k from what iv read, im sort of afraid to do that, but you need to still change the filter every 3k

[CSI_MuNkY]

I switched to Royal Purple myself, and I don't care what anyone says, I noticed a difference, although I have a 3.4L DOHC if that makes much difference at all when it comes to an oil. The car runs smoother and is WAY less hesitant now. Not to mention the better milage I'm getting, it changed from 14.5L per 100 km to 13.3L per 100km, still not great but I have a lead foot. It gets even better if I take it easy, on the highways I'm now getting 10.1L per 100km and I tend to drive around 130-140km/h depending on what the rest of traffic is doing, if i keep it around 115km/h I can get around 9.8L per 100km. Sorry, no imperial conversions right now.

I'm doing my first oil change at the end of the month since switching and I fully plan on switching out all of my fluids for Royal Purple.

As for the additive, don't use it, the Royal Purple website specifically states not to use an additive with their product. My brother uses the additive in his 93 Mazda MX6 as a last ditch effort, it was enough to stop the slightest leak, but what can you expect from a 13 year old ricer?

Amsoil, mobil 1, and royal purple are full synthetics.

sound like that's not a full synthetic oil you're using. well, not with the service intervals you specified anyway...

 

(edit: semi-synthetic is what it may be).

[Prospeeder]

Its just royal purple is extremly exspensive is why i said not to waste money when the same things less exspensive. And your right, im using Senthetic Blend, next oil change im going full

[chadz34]

Funny that should be mentioned, I switched to synthetic too earlier this week. I used Castrol Syntec.

Just like before you're issuing irrelevant statements. OMG THE VALENCE! Stick to what you know...whatever that may be

 

Anyway semi-synthetics are very different from full synthetics when it comes to service interval and care. I change my oil once a year, and the filter every 6 months.

[Prospeeder]

omg whoops i forgot i was using blend, who cares. Older senthetics used to be 7k, wich is what i remeberd, this is the first iv even herd of amsoil with its 15-35k intervals, sorry, sheesh

This could be me, but it's been my experience Castrol sucks. Has anyone else heard this? I thought I remember Shaun back in the day saying something about it.

 

EDIT:

 

Not trying to be a dick but just to back myself up.

Motor Honey is this thick goo, looks like Honey and equally as viscous.

I've seen it before, but I don't remember if its trade name is "Motor Honey" or if that's just what my stepdad called it and the name stuck with me (my stepdad has names for stuff like "gorilla snot" is that really strong yellow-brown glue).

 

No, Syntec is not a "true" synthetic. It has neither a PAO nor Ester base. It's a hydroprocessed mineral ("dino") oil. Hydroprocessed just means it was refined in a way that it's super clean and covers greater viscosity ranges. Hydroprocessed oil is Group III. Conventional mineral oil is Group II. True synthetics are Group IV. The FTC lets Castrol call it synthetic, because hydroprocessed oil doesn't occur in nature, so even though it doesn't fit the *original* definition of synthetic, it's still allowed to be called "synthetic". It's still better than standard Group II motor oil, but it's a ripoff compared to Group IV oils of the same price (like Mobil 1).

 

EDITx2:

Amsoil is 25k or one year.

When used in mechnically sound engine. Replace Amsoil oil filter at 12500 or six-month intervals, whichever comes first(other brands as speciffied by the vehicle manufacture.

 

That's right off the bottle, get the facts straight.

[Pontiac6KSTEAWD]

Dont ever use any Lucas oil products. I have a write up on my computer somewhere that Lucas Airiates (sp) in the motor, fully reducing the coverage the oil can cover in the motor. STAY AWAY. However, there is a product called MotorKote (SP) that I have been hearing and seeing great reveiws on. Its for all mechanical parts (power steering, tranny, motor, difs, etc). Pretty expensive stuff thou, but I have been seeing some great things about it..

[pitzel]

I run Esso Extra XD-3 0W-30 full synth oil. Have approx. 24,000km's/2 years on the current oil change, and everything still looks nice and clean when I pull the dipstick or shine a flashlight into the filler hole. Esso XD-3 0W-30 is nice because it only costs about $4 Canadian per litre at the local Esso bulk dealer, barely much more than a litre of dino oil costs at Wal-Mart.

 

If anything, the Amsoil 25k mile oil change interval is quite conservative with these vehicles if there are no coolant leaks. I have saved at least 5 oil changes (probably will run out to 40-50k miles -- saving 10-15 oil changes) already, and I can't imagine my engine is any worse for wear or sludge.

PROSPEDERS back.....YEY...

 

I switched to Royal Purple 5w30 in my 89 buick 3.1 a couple days ago. The lifter tick is clearing up slowly and cold starts dont sound anywhere near as bad as they did with 10w30 dyno oil.

[Crazy K]

I change my oil once a year, and the filter every 6 months.

and how many miles is that???

 

I'm running castrol syntec

I say between 5 and 7 thousand with full synthetic...... but then again.... thats an oil change every two to three months for me!!!

I think he's gone again too after some things he said to people in private messages.[br]Posted on: March 26, 2006, 12:04:50 AM_________________________________________________

It really varies for me. The most I have gone in a year has been about 28k until I changed it, and it really wasn't that dirty at all when I drained it. Most of the time it's been less than 20k miles before I've done the change.

[luminal67]

look at the inside of an engine running conventional oil compared to an engine running synthetic. I've ran Mobil 1 in my l67 for the past 10,000 or so and when i took it appart for a cam, evrything inside was nice and clean. it looked like new. hardly any of that brown coloring to anything inside.

[THe_DeTAiL3R]

I would personally run a cheaper synthetic (like Mobil1 or whatever), let that clean out the engine the best it can, THEN put in Amsoil/R.P your next oil change.

 

 

 

 

[manitcor]

The topend oils like AMSOil and Royal Purple may be more expensive, however you make up some of that with greatly increased oil change intervals.

 

Do the research, you really can go 10,000+ miles on a single oil change with a high quality filter change every 5k or so with the top oils.

 

Dont listen to what your daddy told you or what the local quick lube says. Technology is much better now and so our the oils and filters provided you get the good stuff.

 

Personally I use AMSOil Series 3000 with an AMSOil or K&N Oil Filter and change the oil every 10-15k with filter changes every 5k miles.

 

How did I arrive at what is safe?

 

I spent a year doing oil analysis on my engine with that setup. I managed to go 20k on one oil change and filter changes every 5k. If you dig around this forum youll find some of my posts about it.
