Was just wondering what oil you would use in my car (see below)
She has covered 155,000 Miles and still drives very well and returns quite reasonable mpg, I change the oil 3 times a year religiously with castrol magnitec ford spec 5-30 fully synthetic. However I did notice in my haynes manual it also had [u]5-40 [/u]as an option. Would this be of any benefit to a higher millage engine or would it cause any problems?
What are your thoughts reguarding using oil additives such as forte oil fortifier etc
I have my concerns using these in engines which use an oil with a low oil viscosity i.e. [u]5-30 [/u]
Many thanks in advance
