## Overview

STP GST60300EN12 Oil Treatment is a 300ml mineral oil-based additive designed specifically for petrol engines. It enhances motor oil with viscosity improvers and anti-wear, anti-friction, and anti-oxidation agents, providing superior protection against engine heat and wear. Perfect for older or high-mileage engines, it helps maintain oil pressure and prolongs oil life, ensuring smoother, quieter, and longer-lasting engine performance.

## Description

STP Oil Treatment for Petrol Engines fortifies motor oil with an extra measure of additives, providing increased levels of viscosity improver plus anti-wear, anti-friction and anti-oxidation agents. STP Oil Treatment for Petrol Engines, a mineral oil based additive, provides extra protection against engine heat and allows oil to maintain key lubricating properties for longer to keep the engine going strong until the next oil change.

Review: Perfect for older simpler engines - I use this in a Ford Capri 2.0 to add a bit of extra zddp to the oil to protect the camshaft. Plus the engine has done 100k miles, so the extra viscosity keeps the oil pressure healthy. It may just be my imagination, but I'm sure the car runs quieter and cooler with this in. I add it to the 10w/40 semi-synthetic oil Ford originally recommended for Pinto engines, and it seems to alter the viscosity to approximately that of a 15w/50 or 20w/50, judging by the oil pressure gauge (and how it flows when I drain it). All in all brilliant for a classic engine, but probably not a good idea to put it in a post-millennial vehicle.
Review: STP GST60300EN12 Oil treatment for petrol engines (300ml) - As servicing mileage is increasing anywhere between 10,000m ~ 20,000m to support your synthetic or mineral oil--I would recommend using STP after every service to improve it's viscosity !! The best way of using it is to boil a saucepan open the STP bottle & let it simmer for about 10 minutes so that the STP is liquid & easier to pour into the engine without wasting any STP is also excellent for older engines where parts are beginning to wear & need better lubrication particularly valve guides & big-end assembly

## Questions & Answers

**Q: Can i use this in my motorbike that has a wet clutch ?**
A: hi this product thickens engine oil would say it would be too thick to use in a wet clutch I use it in an old car with a worn engine think that is what it does best

**Q: Is good for a6 2009 tdi 2.0l ? Automatic?**
A: I have a 2010 VW 2.00 litre auto and works fine on mine.

**Q: When using this product. Do you need to pour the entire bottle to the engine or half etc?**
A: Hello, First of all run a hot bowl of water and stick the bottle in and leave it for 10 minutes,reason for this its as like a set honey. In answer to your question you use the whole bottle at once preferably in a warmed up engine. Simply poor in where you top up oil and start the engine to allow it to idle for around 5 minutes this will allow it to mix with your oil properly whilst the engine is under minimal load.  It's a great product , hope this helps

**Q: Can I use this on a Diesel engine with a dpf**
A: Yes you can - Has no direct influence on DPF performance. Need a fuel additive for that.

### ⭐⭐⭐⭐⭐ Just the job!
*by G***Y on 26 January 2025*

Having bought my granddaughter a 10yo jalopy for her 18th birthday, I decided a tad of engine care wouldn't go amiss! I have used STP additives since I was a poor student myself (many moons ago) and have never regretted it. Prevention is always better than cure! This time the car seems to be happier and running smoothly. Let's hope it stays that way! Remember to closely follow the instructions on the container.
