Here's the Briggs & Stratton link:

Here's 30 weight motor oil. I put it in my B&S lawn mower engine. Get it at Wall Mart. Note you can use synthetic. I will switch after a few more hours.

do you have a link to that, i want to print it out

It sounds like Sears wants to sell priivate labeled 30W "Craftsman" lawn mower oil!

hey stg,
You just had to add the 9mm +p+ ammo as a stand for the oil, nice touch HAHA. I prefer a 44 magnum with 180 gr xtp's at 1850fps for some fun and noise.

yes they did because they even included the part number and this card i can keep in my wallet

Are you running the Mobil 1 "extended" 15k mile guaranteed stuff? I use the Mobil 1 fully-synthetic motor oil and change it every 3k miles. Better safe than sorry.

Yep, extended performance, advertizes 15k, I change every 7.5kish. I'm thinking about going to 10k, but changing filter every 5k.

Synthetic Oil

I started using Mobil One Ext-Perf 10w-30 in my 2001 Nissan Sentra (bought used in 2005) at 48Kmi. I immediately noticed smoother idiling, better pick up, and beter gas mileage (32 combined mpg). Also, installed a K&N air filter and use K&N oil filters. I don't believe in oil additives because it's like adding "Mollasses" into your crankcase.

I filled my mower up Mobil 1 - yeah I know I'm crazy - and I can really tell the difference in the way it idles.

Well, I use Castrol Syntec. Reason being, Toyota uses regular Castrol oil, and since Toyotas have more longevity and less problems than Porsches, Castrol is surely something good!

Really, there is likely to be very little difference between the two synthetics, I would use either one, but no others. Also, I really prefer Mobil gasoline, I get much better mileage.

Anyways, I wanted to add to this -

If you are dealing with an engine that has MANY miles and is ancient, then a synthetic motor oil is not for you. Synthetic oil is able to squeeze into every gap and it will allow your engine to start to drip a little oil. If your engine already drips oil, the DO NOT use synthetic oil; it will create some really big problems. If your engine is fairly new, then synthetic oil is a huge benefit for you engine.

The issue here is cleaning agents. Synthetic oils have cleaners in them which break down and remove sludge and deposits from your engine.

With regular dinosaur juice, in an old engine, where your seals have dried out, become brittle, cracked, etc... that dinosaur juice turns into a gummy sludge and fills in the cracks and crevaces. Over the years, regular oil may seep through a little bit.

Well, when you add the detergents of synthetic oil, plus the extremely slick micro-particles of the oil itself.... you wash out the gum from the seals, which allows the oil to flow freely.... sometimes out onto the driveway!

If you have good, pliable seals and gaskets on your engine, switching to a synthetic won't hurt a bit. However... if you have 100K miles on the motor... I'd probably go with a blended-synthetic designed for high mileage motors instead.


But also, it's true... Idle is better, and so is fuel economy, with synthetic oil, compared to regular. Theres a fairly significant difference between the two, and you can even hear it.


As for fuel additives...
Definitely useful in older vehicles. Marvel Mystery oil in the fuel and crankcase is good stuff. Restore in the crankcase is good stuff.
With new vehicles I'm hesitant, as theres alot of sensors the wrong chemicals could foul. At some point I might be inclined to run some fuel injector cleaner, but quality gas should prevent the need I think.

ahh we dont have the extended preformance in Canada
ony this stuff



EDIT we dont have high preformance but my car needs 5w-20 anyways

Oh,where can I start? First, your logic behind using Castrol Syntec is completely faulty. As you yourself state, Toyota uses REGULAR Cstrol, not Syntec. Porsche uses Mobil1 becauseit meets their engineering specifications. Guess what, those engineeringv specifications have to to with the ENGINE, not every other part of the car. There are are VERY few engine problems or failures related to oil in Porsches or Toyotas. The fact is that almost all reliability issues for both manufacturers are in areas far removed from engine lubrication.

If a Porsche has an engine CPU or wiring failure, a leaky windschield or bad shock absorbers, it has nothing to do with oil.

Second, your cvomparison of Mobil 1 to Castrol Syntec as a synthetic oil is incorrect. Outside of some boutique brands, Mobil1 is the only truie synthetic motor oil on the market. It is based on a Group IV PAO base stock - manufactured in a lab, not derived from petroleum.

Castrol Syntec is a Group III base stock - hydrocracked petroleum. The only reason Castrol can call Syntec syntheic in the United States is because Castrol suceeded in changing the definition of "synthetic" in court.

Face it. You buy Syntec bacause of the pretty bottle.

lmao STG, great comeback!

The dealerships do use Castrol Syntec, if you want to pay the extra, I think it's $40 over the regular oil change price
I change my own oil, thanks!

I'll say this much, Castrol performs great in my car... it was an eye-opener. However, I'll give the Mobil 1 a try next time, on your suggestion... curious if theres any noticable difference. The Mobil stuff is actually cheaper!

Pretty much, I went with Castrol simply because I know the Toyota dealers here stick with it. No other reason really.


Off topic, but what do you use for oil filters? I'm using Purolator Premium Plus filters with the Syntec, and following the 5,000 mile factory recommendation for changes. I hear WIX is good, but I haven't found any around here yet.

and the really cool cap too

porsches also have some of the most soild engines ever because well... its a porsche! you can still find a 65' 911 with the original engine. I don't think that it has much to do with oil just the engineering behind it.

on the oil filters my car has the Honda oil filter by fram in it right now, but when I switch to Mobil1 I am going to also swith to the K&N oil filter

[PorscheGuy997]

First of all, I know of people with 911SC's that have gotten OVER 500,000 miles without an engine rebuild or an engine replacement. My 73' 911 has its original engine with 88,000 miles. Look at the early 911's; notice how they almost always have the original engine? If the engine is replaced, it is never because of an engine failure, but because they want more power. And if the engine did fail, it is because of a driver error or neglect i.e. over rev, not maintaining the engine, etc. Look at some of the club racers; they hardly ever have to rebuild their engine. The new Turbo engine is almost identical to the GT3 Le Mans cars, except without the turbos.

The end.

I though that this thread is about gasoline additives not oil additives or Syntec. oil.

...ya sorry about that, I sort of hijacked it
