Oil additives

[Telegram Sam]

On the enthusiastic advice of my garage man I today bought myself a pack of STP Oil Treatment (I had to look twice since they have changed the packing from the silver grey tin that I last used a long time ago). But I've got a feeling that the oil manufacturers take a pretty dim view of anyone adding anything to their precious products (I use GM 10W-40), so we are caught between a rock and .. What is the Mk 3 Club view on this topic?

If you are using good quality oil and changing it often enough it shouldn't need anything added to it.

New one on me, that. I'll do some digging but if it's that kind of a price for 4 - 5 L it will have to be pretty damn good. Otherwise I'd stick with the GM and change it twice as often!

Standard 10 40 oil is fine. Unless you rant the living shit out of it I'd carry on using what your using. Every 6000 is fine. There's high mileage engines still running ok today having used 10 40 all there life

Yup that's the formula I've been using for the past 223 K miles and it seems to have worked OK though I now change it max every 12 months due to low mileage. Also I've got this thing about taking it extremely easy until the motor has fully warmed up - in theory not necessary but gut feel tells me a cold motor is like me getting out of bed in the morning

Yes that's where the oil viscosity comes in. The Miller's nano oil has been proven to reduce friction from the engine components thus increasing engine power and better mpg

Sounds rather like the STP blurb on the bottle!! I'd give it (Millers) a try if it wasn't so expensive.l

Aye, there's plenty of oils to try. But it all comes at a price.

With regard to cold starts, I drive off at a snail's pace, for the same reasons. Good thing is I live almost a good mile from the main roads, so good time to warm up before joining main traffic. Before I used Castrol GTX high mileage and Magnatec, from now on I'll just stick to GM stuff.

With regard to additives, the only one I've used on the 8v block is the STP Engine Flush, when changing oil a couple of times. I probably wouldn't use any others, unless I had leaks or something. There's an additive for that too, and is a cheaper alternative to stripping the engine down

[btcctroy]

It makes no difference. If you drive of at snail pace putting load low down this is just at bad as revving it cold. Just drive it normal. It will make no difference to how it lasts

>> Low revs + low load. Boss at work has a Porsche, does 100% the opposite when setting off, sounds very impressive but it's painful to think of the wear.

[Cavalier342]

No, light load. I never labour a cold engine, I agree it is just as bad as revving it from cold.
